Criminal Prosecution and Competencies Free Essays

Through movies, we get the impression that police officers have all the right to arrest someone and bring him to court. But the underlying fact in this is that there are some things that must be done before a trial can be reached. For instance, an offender is arrested for committing a crime. We will write a custom essay sample on Criminal Prosecution and Competencies or any similar topic only for you Order Now There are steps in a criminal prosecution which leads to sentencing. During the arrest, the offender is handcuffed and taken to jail. The offender is then taken for booking wherein his photograph and fingerprints will be taken and he will be searched. A strip-search may be necessary at some point. Then, the police will ask about the offender’s personal information such as name, address, date of birth and social security number (American Hunt Saboteurs Association, n. d. ). The next step would be arraignment, which signals the court appearance for a felony or misdemeanor. During this process, the charges to be filed and the penalty applicable once convicted, and the Constitutional rights are recited to the defendant (Nichols, n. d. ). The offender also pleads guilty or not guilty during arraignment, after which the pretrial, readiness hearing and trial dates are set. If the offender does not plead guilty, the next step would be the pretrial hearing. This is the time for both parties to file pretrial motions or issues. Then there would be the discovery. Discovery refers to the information needed for the parties to prepare the case. The next step is motions, wherein both parties can present testimonies or arguments. The readiness hearing will follow. This hearing is mainly held to find out if both parties are ready to proceed (City of Oak, 2003). After these steps, the trial follows. For an offender who pleads not guilty, he will be tried and convicted by either a judge or a jury (American Hunt Saboteurs Association, n. d. ). The judge or the jury decides upon the verdict. This leads to the final step, which is the sentencing. In some areas in the United States, sentencing can be delivered in an expedite manner, or the defendant can return to be sentenced. Before a judge or a jury can put down a sentence, the judge must first hear the sides of the prosecution, victims or their representatives, the defendant and the defense attorney (City of Oak, 2003). Foundational and Decisional Competencies Foundational competencies, which are sometimes called Work Readiness Competencies, refer to competencies which serve as foundation for success whether in the workplace or school. Having foundational skills is very essential especially for workers to be able to learn new industry-specific skills. Foundational competencies are considered fundamental in occupations and industries (State of Minnesota, 2009). Foundational competencies transcend many other forms of competencies, such as ethical competencies, personal effectiveness, work place competencies and so on. Individual and cultural diversity and professional development are also classified as foundational. Take academic competencies as example. The critical competencies that people have learned in an academic setting such as communication, reading and writing, and basic computer skills are necessary in order to succeed in one’s chosen career. Academic competencies are the foundation for other competencies such as occupation and industry specific competencies. Decisional competencies, on the other hand, are categorized under workplace competencies. Possessing excellent decision-making skills is critical in both work place and school. Decisional competencies aid an individual in functioning â€Å"in an organizational setting† (Long Island University, n. d. ). Foundational and decisional competencies can be related in criminal cases, especially ones wherein the defendant suffers from a mental disorder. Foundational competencies can include the defendant’s basic knowledge of the charges and the adversary system as a whole. They also include the ability to â€Å"disclose relevant information to counsel. † Decisional competencies, on the other hand, would include one’s ability to understand legal alternatives and choose among these when necessary (Skeem, et. al, 2004).

Rome Essays (366 words) - Superpowers, Roman Empire,

Rome Greek culture laid the foundation for the Roman Empire. The Roman people wanted to be like the Greek people. For example the Romans made a sculpture of the Greek goddess Aphrodite. The Romans recognized the Greek art and architecture to be very well done. Since the Romans likes these traits of the Greek they used the Greeks ideas and created there own. That was the basis of the Roman Empire. In 64 AD there was a fire in Rome that burned down a large part of the city. When Rome decided to reconstruct they built the city back up in Greek style. They used the Greek architecture, and made it into their own. In 385 AD the Roman Empire fell into the West-Roman Empire and the East-Roman Empire. The two Empires existed until 476 AD when the Western Empire was invaded by the Goths. The Romans used the Greek architecture style, and created their own architecture style. This Roman architecture is well known around the world today. It is seen in many places still as of this time. The Romans created the style of the pillars on the buildings. Architecture is a main part in the development of an Empire. The Romans took the word basilica from the Greek word basileus which means king. The original word means a royal palace. But the Romans made the meaning into a center of business. But also in the basilica they had administration meetings there. This shows how the Romans based their business from the Greek way. The Roman forums were very unique from any other countries forums. The forums were unique not only because of its architecture but on how it represents freedom and its a symbol of democracy to the Empire. The Romans had there own gods, but in 500 BC the Romans came in contact with the Greek gods. Not long after did the Romans adopt the god of the Greek. The Greek culture laid the foundation for the Roman Empire. As you can see the Romans adopted and used many of the Greeks, art, religious gods, and architecture. Because of this the Romans based their Empire on how the Greeks based theirs. History

Assess the significance of Judith Butlers work Essays

Assess the significance of Judith Butlers work Essays Assess the significance of Judith Butlers work Essay Assess the significance of Judith Butlers work Essay The modern significance of the word gender emerged in the 1970s. Its original intent was to pull a line between biological sex and how peculiar ideas and behaviors could be defined as either feminine or masculine ( Pilcher A ; Whelehan, 2004 ) . The ground for utilizing the word gender was to raise consciousness of the hyperbole of biological differences between work forces and adult females. The popularity of this significance for the word gender resulted from the attempts of 2nd wave feminism in the 1970s. This essay examines how 2nd wave feminism attempted to build a grand narrative of adult females s subjugation. It so examines Judith Butler s part to post-modern womens rightist theory through her performative theory of gender and how this fits into post-modern womens rightist arguments. A merchandise of 2nd moving ridge feminism, which began around 1970, was the effort to topographic point adult females within a grand narrative history of their subjugation. One of the seminal authors on this narration was Simone de Beauvoir. Her work in depicting how adult females had become the other in her bookThe Second Sexual activity( de Beauvoir, 1961 ) laid the foundations for what was to come in the 2nd moving ridge of feminism ( Gamble, 2002 ) . De Beauvoir argues that the manner in which work forces think about adult females is merely in relation to their phantasies, that they have no substance of their ain. Unfortunately, for de Beauvoir, adult females have come to accept work forces s phantasies of muliebrity as representing their ain construct of themselves. For de Beauvoir, it was for adult females to gestate of themselves in their ain footings, to take back the power themselves. A unfavorable judgment of de Beauvoir s attack was that it tended to fault adult females for their current status ( Gamble, 2002 ) . The 2nd moving ridge womens rightists of the 1970s, nevertheless, such as Millet ( 1970 ) , pointed to patriarchy as the root cause of adult females s subjugation. It is patriarchy, so Millet argued, that has become a political establishment, and from this flows all the other signifiers of adult females s subjugation. Firestone ( 1970 ) besides took a strong line against patriarchate, comparing adult females s subjugation to a caste or category system. Ideological support for patriarchate, in Firestone s position, has come from establishments such as the household, matrimony along with romantic love. These thoughts are referred to as building a grand narrative , a manner of charting the history and development of peculiar thoughts, in this instance adult females s subjugation ( MacNay, 1997 ) . One of the jobs that much feminist idea has come up against in seeking to supply a grand narrative of adult females s subjugation is that it is hard to efficaciously give all adult females a common individuality ( Whelehan, 1995 ) . If the really thought of gender flows from cultural beginnings, so it is merely natural to reason that gender has different significances in different cultural contexts. How so can a common individuality be posited? Other critics such as Richards ( 1982 ) , analyzing 2nd wave feminism from a broad position, have seen it as a motion that has failed. Richards sees many of the feminist attacks as being utmost and unattractive, and non focussing, as she sees it, on rational argument. She criticises womens rightists for using eccentric statements which do non conform to the normative outlooks of philosophical argument. Further, she criticises feminism for disregarding the obvious differences between work forces and adult females such as adult females s ability to hold kids and thereby showing an unrealistic image of Utopian gender dealingss. Another vivacious watercourse of unfavorable judgment against 2nd moving ridge feminism has been that it assumes that what is required is a reversal in the comparative places of work forces and adult females. In other words, if adult females can take the place of work forces in society so their subjugation will eventually be undone ( Brooks, 1997 ) . Alternatively, nevertheless, post-modernist signifiers of feminism have tended to knock the placing of adult females and work forces in oppositional classs. Post-modernist authors, such as Judith Butler, Brooks argues, assist the feminist argument move on from the expansive narration to the focusing on deconstruction and individuality ( Brooks, 1997 ) . Judith Butler s work as a societal theoretician has been highly influential. Some of the major subjects of her work include of import parts to thwart theory and her unfavorable judgment of the manner in which gender has been constructed ( Clough, 2000 ) . Her discovery work wasGender Troublewhich strongly criticised bing womens rightist theory on gender such as the work of Firestone and Millet. Butler ( 1990 ) points out that feminist attacks have tended to underscore the difference between gender and sex. In these positions sex is seen as a biological fact, while gender is a cultural building. The job for Butler is that this split has gone excessively far, such that it is non possible to analyze how the sexed organic structure is constituted ( Salih A ; Butler, 2004 ) . Rather than dividing gender and sex, so, Butler s work has really collapsed one into the other ( Fraser, 2002 ) . Sandford ( 1999 ) explains that this is achieved by demoing that gender really produces sex. Butler ( 1990 ) asks whether it is possible to speak about the masculine properties of a adult male and so speak about their feminine properties and still be able to impute reasonable significance to the word gender . Butler ( 1990 ) argues that when the thought of woman and man are dispensed with, it is more hard to see how these gendered properties can still be feasible. Butler ( 1990 ) states that gender can non needfully be referred to in footings of these properties, or as a noun, a thing of itself, but instead as a verb. In this sense Butler considers gender to be performative, to be an act which constitutes itself instead than fluxing from some other beginning. The unfavorable judgment aimed by Butler ( 1990 ) at feminist theory is exactly that it has argued there must be a beginning for actions. This means that gender can non be performed of itself ; it must be performedbysomething. Butler ( 1990 ) provides an illustration in the relationship between sexual desire and gender. Freud s account that attractive force comes from biological sex is considered by Butler. She argues that sexual attractive force, instead than coming from sex, is a procedure that is learned over clip, that is a public presentation we work on, non something fluxing straight from biological sex. The political deductions of this statement are critical, particularly for homosexualism. Kirsch ( 2001 ) argues that some people in the fagot motion have accepted the primacy of biological science. This thought is related to essentialism which relies on factors such as the gay cistron to explicate homosexualism. In contrast to this position, a constructionist attack concentrates on the ways in which society encourages certain types of behavior through societal norms. Men and women , within Butler s theory, are no longer essentialist cosmopolitan classs but instead free-floating classs which are socially produced. The norms to which Butler is mentioning are those which see the organic structure as being straight related to the types of sexual desire and patterns that are associated with it ( Salih A ; Butler, 2004 ) . Sexual desires and patterns which do non suit within this matrix are not allowed . In order to understand how sexed organic structures are produced, Butler uses Lacan s reading of Freud ( Salih A ; Butler, 2004 ) . Lacan argues that it is through phantasy that the sexed organic structure is created. Salih ( 2002 ) points out that it is Butler s usage of Freud that is one of her most of import accomplishments. Here, she analyses Freud s thought of the Oedipus composite. This is where the kid is forced to give up its desire for its parents by the incest tabu. Butler reinterprets this by reasoning that the kid desires the parent of thesamesex, but finds that this is forbidden. Sexual activity and gender individualities are so formed from this tabu. Butler argues that everyone s g ender individuality is formed from this homosexual tabu. Butler refers to the formation of gender individuality in footings of melancholy designation ( Salih, 2002 ) . The topographic point where this designation can be seen, harmonizing to Butler, is on the organic structure in the signifier of gender and sex individualities. While Butler s theory of performativity along with her work in post-modern womens rightist theory has been highly influential, it has besides provoked a just grade of unfavorable judgment. Benhabib ( 1995 ) has argued that the decease of the topic, which is at the bosom of Butler s thesis, leads to an incoherent image. Benhabib ( 1995 ) points out that it is hard to believe there is nil behind the mask of gender, that bureau appears wholly absent. In a parallel statement to Benhabib, Kirsch ( 2001 ) makes the point that this negation of the topic has negative effects for thoughts of individuality and corporate action. A sense of collectivity, in peculiar, is frequently seen by those coming out as supplying support. In Butler s theory, nevertheless, there is merely the focal point on the person. To Kirsch ( 2001 ) it seems that Butler s theory tends to cut down the ability of the wider community to supply support to the person. A more generalized unfavorable judgment of modern feminism, nevertheless it is labelled, is that there is a sense in which it is an sole nine. Butler s thoughts associating to the performativity of gender are merely available to a certain restricted group in society: white, middle-class, rational ( Whelehan, 1995 ) . Each feminist sub-movement implicitly creates its ain lists of what can be done, and what can non. Womans, hence, can happen it hard to label themselves every bit womens rightists as there are now many evident bars to entry and negative associations with it ( Whelehan, 1995 ) . Possibly in this sense 2nd moving ridge feminism, as enunciated by Firestone and Millet, provided a vision with which it was easier to tie in. In contrast, post-modern positions, a class in which Butler s work has been put, supply a much more complex and illusive analysis of gender ; even, as some critics would hold it, doing it harder for those trying to populate outside society s norms. It has been argued that theories such as those put frontward by Butler have lead to the demand for a new type of feminism ( Pilcher A ; Whelehan, 2004 ) . This is exactly because postmodernist idea has rejected the grand narrations associated with 2nd moving ridge feminism. As a consequence, adult females may happen it hard to claim the individuality woman as its nature is so contested in postmodernist idea ( Pilcher A ; Whelehan, 2004 ) . This is portion of the job that alleged post-feminism has attempted to turn to. This leads to an effort to reply the inquiry: What gender am I? Viewed through the influence of Butler s theories, it is progressively hard to supply a clear reply. The two replies that are most natural , male or female all of a sudden become disused looks which appear devoid of their old significance. With the subject seemingly removed from the equation, it is hard to put claim to any peculiar gender. Certainly Butler s theory does non connote that both work forces and adult females can go without hinderance across the boundaries of gender, far from it. Naturally society s norms still apply and even evildoings are carried outin relation tothe norms themselves. Ultimately, though, the inquiry comes back to the job of bureau. If it is up to me to take my gender, as I wish, so who is making the choosing? When Butler even rejects the thought of there being an histrion at all, all intending slices from the inquiry What gender am I? In decision, the 2nd moving ridge of feminism brought a expansive narrative position of the history of adult females s subjugation. It pointed to subjugation as a political establishment enforced through societal mechanisms such as the household, matrimony and economic sciences. Critics of this attack, nevertheless, questioned whether it was possible to put adult females up in direct resistance to work forces. Judith Butler responded to the 2nd moving ridge position by fall ining the thoughts of gender and sex into each other. Gender, she argues, is performed, and so the topic in feminist idea, was seemingly destroyed. But, argued critics of Butler, these impressions of gender appear to curtail the political power of feminism, to go forth it toothless, without its topic. Trying to reply the inquiry What gender am I? when viewed in the visible radiation of Butler s theory, leads to a sense of confusion. I could be both, I could be either, I could be neither. Is this freedom, or is it merely excessively free-form? Mentions Benhabib, S. ( 1995 ) . Subjectivity, historiography, and political relations: Contemplations on the feminism/postmodernism exchange.

That same year, Roosevelt got engaged to his fifth cousin once removed, Anna Eleanor Roosevelt (Roosevelt was her maiden name as well as her married one). Franklin and Eleanor were married two years later, on St. Patricks Day, March 17, 1905. Over the next 11 years, they had six children, although only five lived past infancy. Early Political Career In 1905, Franklin D. Roosevelt entered Columbia Law School but left once he passed the New York State Bar exam in 1907. He worked for a few years in the New York law firm of Carter, Ledyard, and Milburn. He was asked in 1910 to run as a Democrat for the State Senate seat from Duchess County, New York. Although Roosevelt had grown up in Duchess County, the seat had long been held by Republicans. Despite the odds against him, Roosevelt won the Senate seat in 1910 and then again in 1912. Roosevelts career as a state senator was cut short in 1913 when he was appointed by President Woodrow Wilson as the assistant secretary of the Navy. This position became even more important when the United States began making preparations to join in World War I. Franklin D. Roosevelt Runs for Vice President Franklin D. Roosevelt wanted to rise in politics like his fifth cousin (and Eleanors uncle), President Theodore Roosevelt. Even though Franklin D. Roosevelts political career looked very promising, however, he did not win every election. In 1920, Roosevelt was chosen as the vice presidential candidate on the Democratic ticket with James M. Cox. FDR and Cox lost the election. Having lost, Roosevelt decided to take a short break from politics and re-enter the business world. Just a few months later, Roosevelt got sick. Polio Strikes In the summer of 1921, Franklin D. Roosevelt and his family took a vacation to their summer home on Campobello Island, off the coast of Maine and New Brunswick, Canada. On August 10, 1921, after a day spent outdoors, Roosevelt began to feel weak. He went to bed early but woke up the next day much worse, with a high fever and with weakness in his legs. By August 12, 1921, he could no longer stand. Eleanor called a number of doctors to come and see FDR, but it wasnt until August 25 that Dr. Robert Lovett diagnosed him with poliomyelitis (i.e. polio). Before the vaccine was created in 1955, polio was an unfortunately common virus that, in its most severe form, could cause paralysis. At age 39, Roosevelt had lost the use of both of his legs. (In 2003, researchers decided it was likely that Roosevelt had Guillain-Barre syndrome rather than polio.) Roosevelt refused to be limited by his disability. To overcome his lack of mobility, Roosevelt had steel leg braces created that could be locked into an upright position to keep his legs straight. With the leg braces on under his clothes, Roosevelt could stand and slowly walk with the aid of crutches and a friends arm. Without the use of his legs, Roosevelt needed extra strength in his upper torso and arms. By swimming nearly every day, Roosevelt could move in and out of his wheelchair as well as up stairs. Roosevelt even had his car adapted to his disability by installing hand controls rather than foot pedals so that he could sit behind the wheel and drive. Despite the paralysis, Roosevelt kept his humor and charisma. Unfortunately, he also still had pain. Always looking for ways to soothe his discomfort, Roosevelt found a health spa in 1924 that seemed to be one of the very few things that could ease his pain. Roosevelt found such comfort there that in 1926 he bought it. At this spa in Warm Springs, Georgia, Roosevelt subsequently built a house (known as the Little White House) and established a polio treatment center to help other polio patients. Governor of New York In 1928, Franklin D. Roosevelt was asked to run for governor of New York. While he wanted back into politics, FDR had to determine whether or not his body was strong enough to withstand a gubernatorial campaign. In the end, he decided he could do it. Roosevelt won the election in 1928 for governor of New York and then won again in 1930. Franklin D. Roosevelt was now following a similar political path as his distant cousin, President Theodore Roosevelt, from the assistant secretary of the navy to governor of New York to the president of the United States. Underwood Archives / Getty Images Four-Term President During Roosevelts tenure as governor of New York, the Great Depression hit the United States. As average citizens lost their savings and their jobs, people became increasingly infuriated at the limited steps President Herbert Hoover was taking to solve this huge economic crisis. In the election of 1932, citizens were demanding change and FDR promised it to them. In a landslide election, Franklin D. Roosevelt won the presidency. Before FDR became president, there was no limit to the number of terms a person could serve in the office. Up to this point, most presidents had limited themselves to serving a maximum of two terms, as set by the example of George Washington. However, in the time of need caused by the Great Depression and World War II, the people of the United States elected Franklin D. Roosevelt as president of the United States four consecutive times. Partly because of FDRs long stint as president, Congress created the 22nd Amendment to the Constitution which limited future presidents to a maximum of two terms (ratified in 1951). Roosevelt spent his first two terms as president taking steps to ease the U.S. out of the Great Depression. The first three months of his presidency were a whirlwind of activity, which has become known as the first hundred days. The New Deal that FDR offered to the American people began immediately after he took office. Within his first week, Roosevelt had declared a banking holiday in order to strengthen the banks and reestablish confidence in the banking system. FDR also quickly created the alphabet agencies (such as the AAA, CCC, FERA, TVA, and TWA) to help offer relief. On March 12, 1933, Roosevelt addressed the American people via the radio in what became the first of his presidential fireside chats. Roosevelt used these radio speeches to communicate with the public in order to instill confidence in the government and to calm citizens fears and worries. FDRs policies helped lessen the severity of the Great Depression but it did not solve it. It wasnt until World War II that the U.S. was finally out of the depression. Once World War II began in Europe, Roosevelt ordered an increased production of war machinery and supplies. When Pearl Harbor on Hawaii was attacked on December 7, 1941, Roosevelt answered the attack with his a date which will live in infamy speech and a formal declaration of war. FDR led the United States during World War II and was one of the Big Three (Roosevelt, Churchill, and Stalin) that led the Allies. In 1944, Roosevelt won his fourth presidential election; however, he did not live to finish it. Death On April 12, 1945, Roosevelt was sitting in a chair at his home in Warm Springs, Georgia, having his portrait painted by Elizabeth Shoumatoff, when he stated I have a terrific headache and then lost consciousness. He had suffered a massive cerebral hemorrhage at 1:15 p.m. Franklin D. Roosevelt was pronounced dead at 3:35 p.m. at age 63. Roosevelt, having led the United States during both the Great Depression and World War II, died less than one month before the end of the war in Europe. He was buried at his family home in Hyde Park. Legacy Roosevelt is often listed among the greatest presidents of the United States. A leader who guided the United States out of isolationism and into victory during World War II, he also created a New Deal that paved the path for an array of services to support Americas workers and poor. Roosevelt was also a major figure in the work that led to the creation of the League of Nations and, in later years, the United Nations. Sources â€Å"Franklin D.

Public Relations Theory and Practice Essay Example | Topics and Well Written Essays - 1250 words

Public Relations Theory and Practice - Essay Example Since the study of organizations is to a large extend theoretical in nature, it is inevitable that we consider the nature and function of theory. Public relations as an example of a theory play a key role in establishing how individuals in an organization communicate and relate to one another (Middleton, Kent & Chamberlin, Bill. 1994p.36). Public relations can be learnt in the context of real-world happenings for example through analysis of events that are happening and discussing them. It can also be learnt through consideration of stories that have been successful and also discussion of unethical practices. Leaning of public relations helps one to develop very good interpersonal relations and hence be able to grow very well in careers such as information and management. Press secretaries, communication specialists and information officers are the specialists of public relations of the government (Middleton, Kent & Chamberlin, Bill. 1994P.205). Their work is to provide the government with the information about the activities of its agencies as well as officials. For example a specialist in the public affairs or a specialist in communication seeks to provide information to the public on travel advisories. Public relations theory and practice has a process which involves four steps and it has a very critical role in ensuring that mass media messages are produced in plenty. Research is a very important tool in an attempt to know the programmes and as well as actions of public relations (Pinsdorf, Marion, 1986P.76). One must know the ethical, moral and legal considerations of public relations as well as understanding the opinions that the public has, bearing in mind the difference between persuasion and propaganda. The British perceive this practice of the EU of having few children due to use of family planning methods negatively over the age of 50s. In Britain, there is a coordinated and a more centralized way of implementing progressive retirements, something which the British over 50s have a negative attitude to. In the EU decentralized and sectoral agreements are used to implement progressive retirements, something which the British over 50s perceive negatively. Britain is very strong economically and has much job opportunities, as opposed to EU. Therefore, it has a negative attitude to enhancement of public relations since this means that the EU institutions will be benefiting from its' resources. Britain is very stable economically as opposed to the EU and EU institutions and hence promoting public relations among the British over 50s and the Europeans will mean that the British will be out-sourcing its' fund to the Europeans and the European institutions. This makes the British over 50s to have a negative attitude over the development of public relations between them and the Europeans. In addition, Britain enjoys a very strong defense system which the British over 50s don't like it to be shared with other countries and institutions outside for example the European and the European institutions. This is also a reason as to why the British over

Huckleberry Finn Essay examples -- essays research papers fc

River of Life and Realism in Huck Finn   Ã‚  Ã‚  Ã‚  Ã‚  In the novel The Adventures of Huckleberry Finn, Mark Twain uses the river to symbolize life and the adventures of Huck to show the realism in the novel. These two elements are shown throughout the book in many different ways. Sometimes one would have to really sit down and think about all the symbolism in this classic novel.   Ã‚  Ã‚  Ã‚  Ã‚  T. S. Eliot stated, “We come to understand the River by seeing it through the eyes of the Boy; but the Boy is also the spirit of the River'; (333). Throughout Huck’s adventure, as he and Jim are traveling down the river on a raft to Cairo, we see the admiration Huck has for the river. He sets it up to be respected as he would a very dangerous but sincere person. He knows everything of which the river is capable. The river has only to desire something to happen and it will. The different currents and movements are the various personalities of the river. No one can predict the next mood that it might take on. For this reason, Huck chooses to admire the powerful and dangerous body and respect it for its personality(338-46).   Ã‚  Ã‚  Ã‚  Ã‚  The only mode of transportation that Huck and Jim have to flow down the mighty Mississippi is a raft . The river controls the voyage of Huck and Jim. It will not let them land at Cairo, where Jim could have been free. It then separates them and leaves Huck at the Grangerford house for a while. Finally, it reunites the two friends and presses upon them the company of the king and duke (Eliot 332). It is their means of escape. “... ‘stead of taking to the woods when I run off, I’d go down the river about fifty mile and camp in one place for good...'; (31). Huck can always depend on the river to take him anywhere he wants to go.   Ã‚  Ã‚  Ã‚  Ã‚  Every move Huck makes seems to get him into some kind of trouble. No matter what the problem, he always goes to that monstrous body of water to solve the mess that he is in. The two friends use the river to slide away from trouble. “...Jim goes again to the raft and lets her go a-sliding down the river';(Angell 131). An example of how Huck uses the river as a safeguard is when he tells Pap he fell in the river in order to escape a great amount of abuse (31). Also, the river repre... ...ealism that was in the world when Twain wrote the book and that same realism is still around today. Even though some times people want to deny it for fear of reality.

Discuss the Difficulties in Seeking to Adopt a Common Social Policy

Assignment 2-Take Home Exam (Question 3, 5 and 6) Question 3 Discuss the difficulties in seeking to adopt a common social policy and social welfare agenda among the E. U. member states. Introduction A social policy is a public policy and practice in the areas of health care, human services, criminal justice, education, and labor. (Malcolm Wiener Centre) In European Union, it has passed a long way to seeking adopt a common social policy and social welfare agenda among the E. U. member states. Caune et al has summarized the process of social policy into three steps followed by the milestone of EU.First stage was to create a common market and keep the national welfare policies. During the first stage E. U. did seek to establish a certain policy, such as freedom of movement for workers and freedom of establishment and equal pay and rights for migrant workers. The second stages was Maastricht treaty that creating Maastricht criteria as new economic policy regime and established ‘sof t law management’. The thirds stage was focus onwards coordination and competition of national welfare policies. The treaty of Lisbon which is the recently moment in E.U. social policy, it defines E. U. seeks to assess the significance of the poverty/social inclusion open method of co-ordination in terms of what it indicates about the EU’s engagement with social policy. From the historically, EU was did a lot of works to creating social policy and social welfare agenda. But E. U. still faces many difficult to making a common social policy among E. U. states. Furthermore, this essay will mainly discuss on the difficult in seeking to adopt a common social policy and social welfare agenda among the E. U. ember states which are based understand and analyzed the history and concept of E. U. social policy. Discussion From the three stages of form a social welfare system, we could found European Union has really well social welfare systems as an example for the rest of the wo rld. It has maintained social equality among EU members which defend weaker market participants and guarantee them acceptable standards of living. However, EU is now face great challenges, such as rapid growth in EU expansion and integration, growing competition among member states for investments.Most of them are now becoming difficult to a adopt a further common social policy EU, such as increasing about personal expectancy, population migration process, growing income inequality and the existing social exclusion. These difficulties are mainly coming from two sources which are national and European level. If EU aims to form a common social policy, they will firstly facing a problem of different social policies pursued by member states. Rutkauskiene indicated that there is† no unanimous opinion about all existing social policy in EU. (Rutkauskiene, 2009) Every member states have their social policy depends on different typology, such as Mediterranean model and antipodean mode l. These different social policy models in the place which lead EU faces a huge challenge-too many different social policy model in the members will hinder the process of adopt a common social policy in EU. One of the objectives of common social policy is maintain social equality among EU member state but each member state has a different economic situation that leading to different budget on social welfare expenditure.Hence, there will be conflict between different countries investment on the social welfare. One of the example are from the EU integration process, employee are free to move to a low cost countries and also employee from poor countries can move to a member state that has a better work condition. The enlargement or integration of European has becoming one of the difficulties in order to adopt a common social policy in EU because it has direct on the social issues, such as unemployment rate and fair work rights.Traser describe enlargement had already, in 2004, caused pu blic anxiety about large numbers of low-skilled and semiskilled workers from the new Member States seeking both employment and benefits in the EU-15, and displacing national workers with cheap labour. (Traser, 2005) The issues about free movement of employee is only one example about the differences of economic situation between member states but it can be a main difficulties for EU to adopt a common social policy because the members state are only stand for their own country and competing with other member states.In the European level, EU are also did a lot of work trying to leading member states participate on the process of adopt a common social policy but it is difficult as well. Since the Maastricht Treaty a concept of ‘soft law’ management measures are used to implementation of the EU activates. This has given to the control measures that are based on voluntarism, education and the sharing of best practices. (Rutkauskiene, 2009) In other world, member’s sta te is voluntary participation in an exchange of information or action.The European council collected all these soft measurement 2000 in Lisbon and give them a name of ‘Open Method of Coordination. (OMC)† (European Council Web) In the European council website explained OMC- set goals are monitored and supervised, best practices are shared and there is a scope to share. (European Council Web) But there are one important feature of the OMC is that goals and achievement are established at the EU level, while the measure and practice to achieving them are left for national governments. Many scholar are debate the disadvantage of this method.OMC is the lack of obligation to implement any agreements, and the lack of sanctions for failing to meet any obligations (Szyszczak, 2006). In other words, EU did not give in to any suggestion about policy to national government, and national government did not need to adequately orient their active measures according to OMC goals. Moreove r, each member states can present their own conclusions on the certain policy areas in their national actions plans, such as pension and health care area. Rutkauskiene has found a greatest number of faults in pension’s area caused by OMC. Rutkauskiene, 2009) Everyone is too different in their personal needs and clamming to adequate for all is not feasible. So a government policy should be set a minimum pension sum to be guaranteed and set of this agreement among EU member states. In other worlds, it is necessary that guidelines for changes in indicator evaluation are set, thereby blocking the way for different understanding about social affairs. From the different argument on OMC policy we can it was mainly established a principle of turning into coordination among EU member state but it facing difficulties turning this policy into an operational manner.Vandenbroucke state the post challenge of Lisbon treaty is EU need an operational social policy. (Vandenbroucke, 2002) Unfor tunately, according to the discussion that the current OMC policy has some disadvantaged that made difficulties for EU to adopt a common social policy. Conclusions This essay has started with an introduction milestone of adopt the EU social policy. The difficulties in adopt a common social policy among EU member states have been compounded furthermore by the fact that large number of state in EU and each of them implementing a different social programs and social policy measures.Then we look on how European Union to dealing with this difficulties of great variety in the social policy systems. We have been chooses the current model to coordinate of social affairs in 2000 at the signing of Lisbon strategy which are Open Method of Coordination. Based on the analysed from different academic literature, â€Å"the main shortcomings of the OMC were identified as the lack of obligation and no sanctions for failing to carry out the activities set out in the agreements reached. (Rutkauskiene , 2009) Hence, the inefficiency of current policy is other main difficulties in adopt a common social policy. At the end, the process of adopt a common social will be forward in the future and the difficulties are also coming continuously at different stages. Reference Arnaudova, F. Z. L. A. A. (2011).

Discuss why  this single market is problematic in the EU with regards to the digital technology sector Introduction The Europe commission in a 1985 white paper launched the single market programme.The main purpose of single market is ‘seeks to guarantee the free movement of goods, capital, services, and people – the EU's â€Å"four freedoms† – within the EU's 27 member states. †(European Commission Web) It was launched as the fundamental economic integration of the EU. It creates large benefit to the enterprise and EU-citizens. The European commission and the EU’s executive arm, has target ‘energy, digital and transport sectors as priorities for depending market integration. †(Egen) In relating to the digital technology sector, the world economic is now more deepening on the digital technology.A 2010 study commissioned by the European Policy Centre from Copenhagen Economics showed that an integrated European Digital Single Market (DSM) would lead to an increase in GDP of at least 4%, with concrete benefits for consumers and citizens. (Economics, 2010) European commissions have already been set in motion about importance of digital single market. For example, Monti report had already highlighted the importance of developing the digital single market, which was also reflected in the digital agenda and the single market act.However, there are still many problem existed in the EU with regards to the digital technology sector. This e ssay will outline of the reasons of why this single market is problematic in digital sector, which are mainly because of less enforce on inappropriate regulation in the member states and cost effectiveness and differences in provision of the infrastructure and ‘old national monopolists’. Discussion In Pablo’s report, which has summaries the European commission need to work more on to build trust and confidence in digital single market.Echeverria has indicated that â€Å"European Commission need to stresses that the consumer rights directive marked an important step forward in terms of increasing legal certainty for consumers and businesses in online transactions, and today constitutes the main consumer protection instrument for online services. † (Echeverria) A single market strategy will require a higher level of legal regulations in regarding to issues such as cybercrime, data privacy and spam while ensuring free movement and the possibility of transacti ons on the internet.Otherwise this single market will be a problematic in digital sector because of the existence of a patchwork of different legal provisions and barely interoperable standards and practices. Also the consumer can’t access the full benefits from this strategy if this regulation is poor. European commission’s report of building the digital single market has identified more and more pollution is using the digital technology now. (Commission, 2011) Peoples are now using more internet service to making a convenience life, such as the online cross border trade.Moreover the digital single market will allow citizens to have access throughout the EU to all forms of digital content and services. So in order to creating single market digital sector, if people are not use digital service in a safety environment then there will be a data protection problems. The other reasons of why  this single market is problematic in the EU with regards to the digital technol ogy sector, which is cost effectiveness. In Zuleeg’s report has determine that a single digital market will require large scale investments in fixed and mobile networks, with much of this investment needing to come from private operators. Zuleeg, 2012) Especially in the European finical crisis period, Europe government and private operator will need to have spent more to support this investment by developing new investment vehicles and guarantees. Michelle Egan also defines a digital single market is a long way of investment and still have many barriers now. (Egan) But the single market in digital sector will improve productivity and contribute to increasing Europe’s medium to long term competiveness. It also brings out benefit beyond the economic which it can help some societal problem, such as fragmented labor market and environment problems.According to all of this facts, we can finding the single market can bring large benefit to citizens and social but it will nee d to put extra investment by government and private operator. So this single market will bring out a conflict between internal users and external stakeholders because of cost effectiveness. A study by Copenhagen economic has list out â€Å"there is a range of national and international operators, totalling close to 100 mobile operators. â€Å"(Copenhagen economic) In the Australia digital sector there are mainly one operator provide the most mobile and internet infrastructure which are Telstra.The digital sector is fragmented in European compared with other countries. The most of the digital companies are competing on a national scale instated of across borders. None have continent-wide operations and provide difference in provisions of infrastructure. One of the example is there are still less operator can provide mobile service across borders and also with a high roaming fees. However the single market strategy in digital sector is trying to integrate these companies into one gr oup.This single market strategy may become problematic in the digital technology sector because a fragmented supplier industry may hamper certain developments. From the overall finding, we can operator is the main stakeholder with a large impact on the digital sector. The study by Copenhagen has further explained this fact as â€Å"a lack of market consolidation with ‘old national monopolies’ keeping their strong position in local markets due to government protection in the past. â€Å" The operators are stress on their profit and ignore the importance of single market.One of the major benefits of European single market is increasing competition, leading to lower prices and better welfare for consumers and society as a whole. But the operator has main power in the national market and can refuse price convergence. Conclusion At the end, the single market in digital will have large impact on European economy either in public sector or employee or consumers or producer s ides. But according to the nature of digital technology sector which is fragmented industry and investment barriers so the single market has being a problematic in this industry.Reference Completing the internal market White paper from European Commission to European Council (1985).

Question 6 what are the problems to be encountered in forming a European sense of identity among the citizenry of the EU? Introduction A sense of a national identity is â€Å"the person's identity and sense of belonging to one state or to one nation, a feeling one shares with a group of people, regardless of one's citizenship status. (Smith, 1993) Usually, these are nation-states but it also can implied an entity group of European Union. McCormick writes sense of European identity as â€Å"a related term of Europeanism refers to the assertion that the people of Europe have a distinctive set of political, economic and social norms and values that are slowly diminishing and replacing existing national or state-based norms and values. †(McCormick, 2010) Johan Borneman indicates the practices of Europeanization in term of languages, money, tourism and sex and sport. Borneman 1997) European Union are getting practice on this through the creation of the European single market, the expanded the European Union from twelve members in 1985 to twenty-seven members in 2007 and link the legislative and policy frameworks of EU with European identity. As we explained before EU has a long history of this integration process but there are still many problems encountered in forming a European sense of identity among the citizenry of the EU. There are especially in some countries are having this problems such as British.Moreover, this essay will discuss on the main problems that are in forming a European sense of identity among the citizenry of the EU. It also will consider some examples in English. Discussion Medrano has summarized the main problems into three section which are â€Å". 1) conflated behaviour in referenda on reform treaties of the European Union, support for European integration, and identification with Europe, 2) conflated different dimensions of European identity, and 3) failed to unpack the various meanings that citizens a ttach to the idea of identification with Europe† (Medrano, 2010)In the detail, the first problems are mainly concerned on the public debate on European identity. Many people see no opportunity to influence supranational decisions effectively because there are lacks of intermediary actor primary covering European issues. In the public, the media or journalists are both have lack of supporting on EU news. Vreese said â€Å"It is difficult to ‘sell’ an EU story. † (Vreese, 2004) Medrano has asked many journalists do you agree you play an important role in ‘crating a European identify’. (Medrano, 2010) The most of them unanimously agreed that the answer should be ‘NO’.Some journalists believe their role is to create engagement and interest and not to influence identity. One of the examples is in British, the public opinion is divided and the country is becoming the most of skeptic members in EU with regards to EU policy of common curre ncy and the enlargement. There is other problem influencing public opinion about Europe, such as difference in social-demographic characteristics. Most of researcher has find men being more supportive of Euro-pan integration and higher levels of education are associated with being more positive towards the EU.The second problems listed by Medrano, can be described as there are having many dimensions of European identity either by national or citizen. If there are too many dimensions of European identity that will results a lack of precision use in the use of the sense of European identity. The official dimensions of European identity is a precondition for a democratically legitimise European Union with feeling of belonging together of the people living in the member states, including the awareness and the support of common values, achievements and aims.But in related to a real case the European identity is far lagging behind national identity. Fukuyama has given one example of Franc es created a strong national identity by built around the French languages. (Fukuyama, 2012) In order to compared within the EU’s dimension, EU are more stress on political and policy identity but the nation’s dimensions are more focus on culture and social level. EU has 27 members within different culture and religion. These countries have already built on different level of national identity.EU is now trying to integrate this national identity into one common identity which is European identity. So EU needs to conflate different dimension of European identity. The third problems is failed to consider the citizen’s ideal about European identity. The EU defines concept of European identity are most physically based, such as free movement of goods and service. But the officials should to promote a sense of belonging to Europe citizens emotionally. Medrano stated there are lacks of identification with Europe among citizens are mostly interested in the emotional di mension of identification. (Medrano,2010)Besides of Medrano’s measured three problems, there are still many other problems in order to create a sense of European identity. One of these problems are EU has less use any knowledge or instruments of identity policy to deliver the sense of European identity, such as education. Walkenhorst writes â€Å"without a sense of commitment and knowledge of citizenship rights the European peoples cannot establish a democratic identity in the sense of supporting the EU as a legitimate political system†. (Walkenhorst, 2004) EU also will not being able to demonstrate its benefits for the European citizen without using an instrument of identity policy.For instance, provide more education or program on spread the sense of European identity will also help to avoid the problems of different religions. EU has different religions identity, such as Christian and Muslim. The concept of European identity need to consider the ideal of multicultur alism and democracy. Conclusions This essay draws an analysis of the problems encountered in forming a sense of European identity which are based on an understanding what is a sense of European identity and how could generate a sense of identity.Since the firstly forming a European Union, EU are trying to creating a sense of European identity. A sense of national or regional identity is an emotionally feeling belongs to a group. EU did a lot of work that letting people are physically feeling of European citizen, such as free movement of people and goods. One of the examples, are Eurostar given people are more mobility in traveling around European. However, EU is now facing problems on ignored the citizen’s emotionally feeling of European identity and conflicts of different dimension about European concept of identity.Each member state and citizens has different dimension about European identity. The best way to solve this problem is using accurate instrument to spread the ide al of European identity, such as education and media. But the fact is there is lack of use media and education that results a problems in forming a sense of European identity. Reference Adrian Favell, E.

Synthesis of Salicylic Acid and Potentiometric Determination of Its Purity and Dissociation Constant

Synthesis of Salicylic Acid and Potentiometric Determination of its Purity and Dissociation Constant ————————————————- Abstract The purpose of the study is to synthesize salicylic acid from the ester, methyl salicylate, and determine the acid’s dissociation constant and purity. The ester was converted to salicylic acid by base hydrolysis. The products were refluxed and recrystallized, to ensure maximum purity, and filtered, dried, and weighed. The melting point of the product was determined using a Fischer-Johns melting point apparatus. The acid then dissolved in separate beakers with 95% ethanol and water and titrated with 0. 050 M NaOH, previously standardized with potassium hydrogen phthalate, through potentiometric titration. The pH after addition of base was measured and plotted against the volume of titrant added using three different plots. Results show a 61. 0% yield and the melting point differed from the theoretical by a range of 3. 11-6. 83%. The pKa calculated was 2. 865, differing from the literature value of 2. 98, by 3. 86%. The theoretical purity of the sample was 100. 0%, which differed with the experimental one by 1. %; the experimental purity is 101. 7%. Potentiometric titration proves to be adequate in the determination of the acid dissociation constant and purity of a sample. Aside from that, the synthesis proved adequate given the high purity of the product. ————————————————- Keywords : acid dissociation constant purity melting point ester INTRODUCTION Potentiometric methods of analysis are based on measuring the potential of electrochemical cells without drawing much, appreciable current. For centuries, potentiometry has been used to locate the endpoint in most titration set-ups. Skoog, et al. , 2004). Potentiometric methods offer a myriad of advantages, its main advantage being its low operational costs. Voltmeters and electrodes are, generally, far cheaper than most modern scientific instruments. Models suitable for direct potentiometry in field work, away from the laboratory, are inexpensive, compact, and easy to use. Essentially nondestructive of the sample, i. e. , insertion of the electrode does not drastically change the composition of the test solution (except for the slight leakage of electrolytes from the reference electrode), electrodes are relatively free from interferences. Stable potential readings are attained fairly rapidly and voltages are easily recorded as functions of time. Finally, the wide range of analyte activities, over which some of the available indicator electrodes exhibit stable, nearly Nernstian responses, represents an important advantage (Day and Underwood, 1991). Potentiometric titrations involve measurement of the potential of a suitable indicator electrode as a function of titrant volume. This indicator electrode is speecific to the hydronium ion, H3O+. It offers adavantages over direct potentiometry in that it is not dependent on measuring absolute values of Ecell. This is due to having the measurement based on the titrant volume that causes a rapid change in potential near the equivalence point. This makes the process relatively free from the juction potential uncertainties as this potential remains approximately constant during the titration process. Instead, the titration results depend heavily on having a titrant with accurately known concentration. The instrument merely signals the endpoint and behaves like a regular chemical indicator. Aside from that, the reference electrode potential need not be known. Most importantly, ionic strength effects are not important in the titration procedure because the result is analyte concentration, even if the electrode responds to activities. The dissociation of a weak monoprotic acid is given by the equation HA – H+ + A– (1) [H+][A–] [HA] where HA is the monoprotic acid, and A– is its conjugate base. The corresponding equilibrium constant for this acid dissociation is defined as Ka = (2) Ka[HA] [A–] which, when seeking to find [H+], rearranges to [H+] = (3) Prior to the equivalence point, before any titrant was added and the analyte is the only species present in solution, the pH of the system is calculated from the concentration of that analyte and its dissociation constant. In the case where a weak monoprotic acid is being titrated with a strong base, subsequent addition of the titrant will cause a reaction to occur between the acid and the base. HA + OH– > H2O + A– (4) The presence of the acid and its conjugate base in solution will cause the formation of a buffer solution, which are solutions that resist a drastic change in pH, should a strong acid or base be added to the system. At these points, the slope of a constructed titration curve is at its minimum. This is the pre-equivalence point. There is a point during the pre-equivalence point region wherein both the acid and its conjugate base are present in equal amounts. This occurs when half of the acid has been neutralized, or when the titration is at the half-equivalence point. At this point, the buffering capacity of the system is at its maximum. Aside from that, simplifying Eq. 3 at this point by inspection, the [H+] is equal to that of the Ka. Taking the negative of the logarithm of both sides, one will be able to get the relation pH = pKa (Skoog, et al. , 2004). Thus, the dissociation constant may be computed through determining the pH at half-equivalence point. This experiment will use salicylic acid as the analyte. Salicylic acid, Fig. 1. Salicylic acid is a weak monoprotic acid, capable of releasing the acidic hydrogen connected to the –COOH group. The hydrogen of the phenol group is hard to release because the oxygen is stabilized by resonance. Salicylic acid is a naturally occuring substance, usually produced by plants. It is found mainly in the willow's leaves and bark. The pure acid possesses several useful medicinal properties. It is an antipyretic (fever reducer), analgesic (pain reliever) and anti-inflammatory (swelling reducer). However, pure salicylic acid makes for an extremely unpleasant medicine. Salicylic acid contains two acidic functional groups, the phenolic (C6H5OH) and the carboxylic acid (RCOOH) groups. These groups cause the acid to be an irritating substance that burns the delicate lining of the mouth, throat, and stomach, hence its esterification to acetylsalicylic acid or aspirin, before ingestion as analgesic (Reed College, 2009). Esterificaton is the process by which a carboxylic acid is transformed to an ester. Esters are organic compounds that are derived usually by reacting a carboxylic acid and an alcohol. The general formula for esters is with the RC=O group derived from the parent carboxylic acid, and the –OR’ group from the parent alcohol. The mechanism for the reaction of the alcohol and carboxylic acid to form the ester is as follows: Fig. 2. Mechanism of Esterification from a Carboxylic acid RCOOH and alcohol R’OH Esters may also be synthesized by reacting the carboxylic acid with other reagents such as SOCl2 to form the acyl chloride, which will then be treated with an alcohol in pyridine, to esterify it. Esters are among the most widespread of all naturally occuring compounds. Many esters are pleasant-smelling liquids that are responsible for the fragrant odor of fruits and flowers. For example, methyl butanoate is found n pineapple oil and isopentyl acetate is a constituent of banana oil. The ester linkage is also present in animal fats and other biologically important molecules. The chemical industry also uses esters for a variety of purposes. Ethyl acetate, for example, is commonly used as a solvent while many dialkyl phthalates are used as plasticizers to keep polymers from being brittle (McMurry, 2004) . Methyl salicylate is produced by many plants. It was first isolated from wintergreen leaves, Gaulthea procumbens, and is commonly known as oil of wintergreen. Fig. 3. Methyl salicylate An ester of salicylic acid and methanol, it masks one of the acidic hydrogens in salicylic acid by replacing it with a methyl (CH3–) group. Hence, it is a relatively unreactive compound that does not release salicylic acid efficiently into the body. It is, therefore, not an effective analgesic, or pain-killer. However, it is added to many products, notably for its fragrance, especially root beer and liniments. In order for it to be activated, methyl salicylate must be converted to salicylic acid by organic synthesis, specifically through saponification, a process not unlike that undergone by animal fats to become soaps (McMurry, 2004). In this experiment, salicylic acid will be synthesized from methyl salicylate by base hydrolysis. Its dissociation constant will also be measured through potentiometric titration. Likewise, the percentage of purity the salicylic acid used in the reaction will be likewise determined. METHODOLOGY In synthesizing salicylic acid, 1. 2 g of sodium hydroxide (NaOH) were dissolved in 7 mL water in a round bottom flask.. Half of a milliliter (0. 5 mL) of methyl salicylate was added to this mixture. The mixture was then efluxed for 15 minutes and cooled to room temperature. One-milliliter increments of 3 M sulfuric acid (H2SO4) were added until the formation of a white precipitate, salicylic acid. Half of a milliliter (0. 5 mL) of the acid was added to ensure complete precipitation of the product. The mixture was then cooled in an ice water bath with a temperature of at most 5 °C for the reaction to subside. The product was then filtered and rinsed with cold water, and recrystallized in wat er. The solids were then filtered on a pre-weighed filter paper and air-dried in the locker. When dried, the solids, along with the filter paper, were weighed and the melting point determined. Two hundred and fifty milliliters (250 mL) of 0. 50 M stock sodium hydroxide (NaOH) solution was then prepared. From this solution, 250 mL of 0. 050 M standard solution was prepared for the titration. This solution was then standardized with 0. 2000 g 99. 95% potassium hydrogen phthalate (KHP) and phenolphthalein as indicator to the pale pink endpoint. Two more trials were done. Three samples of pure salicylic acid were weighed at approximately 0. 000 g and placed in three separate 250-mL beakers. A minimum amount of 95% ethanol was then added to dissolve the acid, and was diluted with 50. 00 mL distilled water. The electrode was first calibrated such that it would relate the developed potential to the pH. At this point, the potential would be measured as pH when increments of the titrant are successively added. The base burette, pH meter, and magnetic stirrer were set up according to Fig. 6. Fig. 6. Potentiometric titration set-up A spin bar was place inside the beaker with the sample solution. The electrode was also positioned such that it would not get hit with the spin bar. The pH of the set-up was first measured prior to addition of base. For the first trial, 1. 00 mL of the titrant was added to the analyte and the pH recorded. This was done until the pH was 11. 50. From there, the equivalence point was approximated based on the volume of the titrant that caused a large change in pH. For the two succeeding trials, 1. 00 mL of the titrant was added to the analyte. At  ±5. 00 mL of the equivalence point, the volume of titrant added was reduced to 0. 0 mL increments. At  ±3. 00 mL and  ±2. 00 mL of the equivalence point, it was further reduced to 0. 20 mL and 0. 10 mL, respectively. The titration contnued beyond 5. 00 mL of the equivalence point using 0. 50 mL of titrant until the pH registered was 11. 00. RESULTS AND DISCUSSION Methyl salicylate reacts with a strong base in the following manner: Fig. 4. Base hydrolysis of methyl salicylate The methoxy group of the e ster is substituted by the hydroxide ion through nucleophilic acyl substitution. The hydroxide attaches itself to the carboxylic carbon. A fast proton transfer from the hydroxide to the methoxy group occurs such that the methoxy gets protonated and leaves the substrate. The sodium ions stabilize the negative charge of the salicylate ion predominantly found near the two oxygens of the ion. The solution was then refluxed to prevent loss of material and to prevent the inclusion of impurities in the product. After cooling to room temperature, 1. 00 mL of 3M sulfuric acid (H2SO4) until salicylic acid starts precipitating as a white solid. To complete the precipitation, 0. 50 mL of the strong acid was added to the mixture. At this point, the salicylate ion is protonated and the final product, salicylic acid, forms through the reaction: Fig. 5. Protonation of the phenolate and carboxylate groups of the salicylate ion The flask containing the precipitate was then doused in cold water to stop the reaction. Cold water was used in rinsing the solid after filtration to wash out impurities that were insoluble in the solvent. The solid was recrystallized in hot water. Dissolving the solids in hot water generally increases the solubility of the substances, hence the solids dissolve along with the soluble impurities. The mixture was then allowed to cool slowly. As the solution cools, the solubility of the compound (and of the soluble impurities) decreases, the solution becomes saturated with the desired compound, and the compound begins to crystallize. Because formation of crystals is a highly selective process that usually excludes foreign molecules, only crystals of the desired compound form. Because the soluble impurities are present in smaller amounts, the solution never becomes saturated with the impurities, so the impurities remain in solution even after the solution has cooled. Removing the solution from the crystals thus removes the solvent and the soluble impurities from the desired crystals. A final rinse of minimum ice water ensures the displacement of the impurities still clinging on the surface of the product (â€Å"Recrystallization,† accessed 6 Sept 2010). After it was recystallized, the solid was filtered again in a pre-weighed filter paper. The filter paper used in filtering the solid weighed 1. 0349  ± 0. 0002 g. The mass of the dried product and the filter paper was 1. 3610  ± 0. 0002 g; this means that 0. 3261  ± 0. 0003 g was synthesized. Theoretically, with methyl salicylate as the limiting reagent, the mass of salicylic acid should be 0. 5400 g. Computing for the %yield, would give 61. 0%. In the determination of the melting point, the observed range of the melting point was 150-156 °C. Comparing with the theoretical value, 161 °C, the relative error lies within the range 3. 11-6. 83%. Therefore, the synthesized salicylic acid has a high purity as exhibited by the magnitude of the relative error. This could justify the %yield given that recrystallization might have caused a loss of material due to the increase of the number of steps involved. It should be noted that in organic synthesis, steps leading to the target molecule do not give 100% yield, hence, increasing the number of steps would decrease the %yield. Aside from that, the low yield could be attributed to the accidental rapid cooling that occurred during the recrystallization process. In a titration curve, there are three important regions: pre-equivalence point, equivalence point, and post-equivalence point. For the titration of salicylic acid with NaOH, the pre-equivalence point is characterized by the dependence of pH on the concentration of salicylic acid. Let salicylic acid be HA; prior to addition of the base, the pH can be calculated by the concentration of HA and its acid dissociation constant, Ka. When the base is added, HA reacts with the hydroxide ion (OH– ) according to the Eq. 4 stated above. Therefore, one has a buffer solution comprised of salicylic acid and salicylate. At equivalence point, all of the acid has been converted into its conjugate base. This base will hydrolyze with water through the reaction A– + H2O > HA + OH– (6) reforming a small portion of the acid. At the equivalence point, the slope of the titration curve is at its steepest. The pH at this point is dependent upon the conjugate base formed and its base dissociation constant, Kb. Beyond the equivalence point, the post-equivalence point, the pH is dependent on the concentration of the excess titrant added. This is because the contribution of the conjugate base is very small and, therefore, negligible compared to that of sodium hydroxide. However, salicylate is still the dominant species of salicylic acid present in solution. A distinction between equivalence point and endpoint should be established when titrating. Skoog, (2004), states that the equivalence point is the point in titration where the amount of titrant added is chemically equivalent to that of the analyte in solution. The endpoint is a point during titration wherein an observable change signals that the amount of titrant added is chemically equivalent with that of the analyte. The endpoint may not necessarily coincide with the equivalence point, especially in neutralization titrations. It may come earlier or later than the equivalence point, depending on the indicator used. This difference pf volume at equivalent and endpoint is known as titration error. In potentiometric titration, no chemical indicator is required. Instead, the endpoint is characterized by the drastic change in pX, measured by the electrode. X may be H3O+, OH–, a cation or anion, or any substance participating in the titrimetric reaction (Day and Underwood, 1991). In this case, the volume of titrant that contributes to the greatest change in pH is the volume required to completely titrate the salicylic acid in solution. Thus, the increments of addition of titrant are narrowed down as the equivalence point is reached because that way, the equivalence point will not be missed. Aside from that, the exact volume of titrant required for complete reaction of the analyte would be detected. Prior to titration and dilution with water, the salicylic acid was dissolved with a minimal amount of 95% ethanol. Salicylic acid is sparingly soluble in water, a polar solvent that can hydrogen-bond with solutes that can hydrogen-bond with its molecules. This is due to the acid having more than 6 carbons increasing its non-polarity, although it has oxygen that can form hydrogen bonds with water (McMurry, 2004). Adding ethanol reduces the polarity of the solvent, facilitating dissolution of the acid. It was noted that some of the acid reprecipitated upon addition of water. Thus, a minimum amount of 95% ethanol was again added to dissolve the acid. In the experiment, the electrode was also not lowered while the bar was spinning as air bubbles would adhere on its surface causing an error in the measurement of pH. Constant stirring is important in potentiometric titrations, as in other types of titrimetric analyses. Stirring is done because it will cause the titrant to react not just with the surface of the analyte where it dropped but with the entirety of the analyte solution. This way, the reaction will go to completion and minimal error will be observed. The volumes used for standardization of NaOH with KHP as primary standard are tabulated in Table 2 in the Appendix. Standardization of sodium hydroxide gave 0. 04633 M NaOH. This value was used in the determination of the percentage of purity (%purity) of the salicylic acid sample. For the determination of the equivalence point volume, three plots were done for each trial. The first plot is the graph between pH vs. volume of titrant. The second is the first derivative plot with which ? pH/? V was plotted against V’, where ? pH and ? V are the change in pH and the volume added between two consecutive readings, respectively, and V’ is the average volume between two consecutive readings. The third plot is the second derivative plot between ? 2pH/? V2 and V†. The ordinate of the graph, ? 2pH/? V2, was obtained by taking the quotient of the difference between two consecutive readings of ? pH/? V, and ? V, whereas V† is the average of the two consecutive readings of V’. Only two trials were done because of the inadequacy of the time. The graphs for the first trial are: a) (b) (c) Fig. 7. Titration Curves for the First Trial. (a) pH vs Vtitrant; (b) ? pH/? V vs V’; (c) ? 2pH/? V2 vs V† MNaOHVNaOH at eq ptFWsalicylic acid Gsample The graph for the second trial may be found at the Appendix. Either of the three graphs of Figs. 7 and 8 may be used in the determination of %purity for each trial. The equation used for determining the %pu rity, specifically for this experiment is %purity = x 100 (7) Thus, the volume of titrant used at equivalence point is required for the calculation. The interpolated values of the volume at equivalence point are tabulated in Table 3 in the Appendix. Calculation of the mean %purity is 101. 7%, having an error of 1. 7%, as the theoretical value is 100. 0%. The pKa is based on the pH at half-equivalence point by virtue of the derivation of Eq. 3. Onle Figs. 7a and 8a may be used for the determination of pKa as the other four do not directly give the pH at each point. The interpolated values for the pH at half-equivalence point is tabulated at Table 3 in the Appendix. The experimental pKa is 2. 865. Therefore, the Ka of the acid, given Ka = –log[Ka] (7) or Ka = 10–pKa (8) is 1. 3646 x 10–3. The theoretical pKa is equal to 2. 98. Thus, the pKa value gave rise to a 3. 86% error. Statistical analysis of the results shows the following results: Table 1. Statistical Analysis of the Results | Range| Standard Deviation| %purity| 15. 7%| 11. 1%| pKa| 0. 21| 0. 148| | Relative Standard Deviation (RSD), ppt| Confidence Int ervals (95% confidence)| %purity| 109. 1| 101. 7  ± 99. 7 %| pKa| 51. 8| 2. 865  ± 1. 334| The RSD of %purity is relatively large such that the values have low precision. Aside from that, the confidence intervals for the mean is also large such that it almost has the same order of magnitude as that of the mean. This means that the mean exhibits very low accuracy. With regards to the pKa, the RSD showed a low value, only 51. 8 ppt, implying high precision amongst the values. On the other hand, the mean value shows low accuracy because of the magnitude of the confidence intervals. These errors could be attributed to the number of trials. Due to inadequate time, the group was only able to do 2 trials, one less than the prescribed number of trials. CONCLUSIONS The experiment aimed at synthesizing salicylic acid from methyl salicylate and determining the acid dissociation constant Ka of the acid along with its purity. Organic synthesis provided a 61% yield of the acid, a relatively low yield. However, the purity of the acid can be classified as high due to the observed melting point range’s precision with the theoretical one; the %differenceis only 3. 11-6. 38%. The results of the potentiometric titration show that the salicylic acid used was 101. 7% pure, a value greater than the purity, which is 100%. The Ka, expressed as pKa, obtained was 2. 865, 0. 035 units less than the theoretical value, which is 2. 98. Though the %differences are low, the accuracy of the computed values is questionable given that the confidence intervals for the %purity and pKa are  ± 99. 7 and  ± 1. 334, respectively. These errors can be attributed to the number of trials done, which is two, due to the slow stabilization of the pH meter readings that resulted in a long period of titration. Thus, it can be concluded that potentiometric titration is an effective way of determining the acid dissociation constant of a sample. It is recommended that a better pH meter be used in the measurement of the pH and that solutions used be titrated immediately. REFERENCES [1] Day, R. A. and A. L. Underwood. (1991).
