What Is Titration

Titration is the process in which one solution is added to another solution such that it reacts under conditions in which the added volume may be accurately measured. It is used in quantitative analytical chemistry to determine an unknown concentration of an identified analyte. Titrations are most commonly associated with acid-base reactions, but they may involve other types of reactions as well. Titration is also known as titrimetry or volumetric analysis. The chemical of unknown concentration is called the analyte or titrand. A standard solution of a reagent of known concentration is called the titrant or titrator. The volume of titrant that is reacted (usually to produce a color change) is called the titration volume. How a Titration Is Performed A typical titration is set up with an Erlenmeyer flask or beaker containing a precisely known volume of analyte (unknown concentration) and a color-change indicator. A pipette or burette containing a known concentration of titrant is placed above the flask or beaker of an analyte. The starting volume of the pipette or burette is recorded. Titrant is dripped into the analyte and indicator solution until the reaction between titrant and analyte is complete, causing a color change (the endpoint). The final volume of the burette is recorded, so the total volume used can be determined. The concentration of analyte may then be calculated using the formula: Ca CtVtM / Va Where: Ca is the analyte concentration, usually in molarityCt is the titrant concentration, in the same unitsVt is the volume of titrant, usually in litersM is the mole ratio between the analyte and reactant from the balanced chemical equationVa is the volume of an analyte, usually in liters

Childhood Obesity Essay - 2386 Words

Childhood Obesity Introduction The past several decades have seen an escalating trend in the rate of childhood obesity not only in the United States where 25%-30% of children are affected, but also in many of the industrialized nations. Childhood obesity has continued to be a major issue in the public health care system. The economic cost of the medical expenses as well as the lost income resulting from the complications of obesity both in children and adults has been estimated at almost $100 billion (Barnes, 2011). Overweight children are more predisposed to the danger of becoming overweight in their adulthood unless they ensure healthier eating habits and exercise. It is worth noting that the current lifestyle in which many children†¦show more content†¦Greek physicians are credited for making the observation that infertility and infrequent menses in women was caused by obesity. About five centuries after Hippocrates, Galen who was a Roman physician made a distinction between immoderate and moderate for ms of obesity. It is supposed that the immoderate form was an anticipation of what is currently classified as morbid obesity (Bray, 2009). Though clinical observations made in the ancient times had brought to light the risk of diabetes and sudden death associated with obesity, the significance of excess mortality and morbidity caused by obesity has only received full appreciation more recently. Data obtained as early as 1901 indicated that people with excess weight, particularly around the abdomen had a shortened life expectancy. Further systematic studies have confirmed this risk and these results led to the World Health Organization classifying obesity on the basis of increasing BMI (Bray, 2009). Epidemiology According to the statistics gathered since the 1960s, the prevalence of childhood obesity has been on the rise with the years between the 1980s and 1990s indicating a three times increase from nearly 5% to almost 15% for both children and teens (Centers for Disease Control and Prevention, 2011, p. 42).

Thomas Jefferson Against His Republican Ideals Essays -

Thomas Jefferson: Against His Republican Ideals While Thomas Jefferson was President of the United States, some of his actions conflicted his beliefs and the beliefs of his supporters in the Republican party. For example, he was elected as a highly pacifistic President, but he ended up leading the country toward war. War came about when more money was being given to piratical Algiers than it would have cost to fight a war. This caused Jefferson to rethink his ideas about involving the nation in war. The showdown finally came in 1801. The Pasha of Tripoli declared war on the United States indirectly, and Jefferson was forced to make a decision against his own beliefs - his pacifism, his criticism against big-ship navies - all faded before him. He sent the nations infant army to the shores of Tripoli and, after 4 years of fighting, Jefferson was finally able to sign a peace treaty from Tripoli. Also contrary to his own thoughts against huge navies, Jefferson ordered that two hundred tiny gunboats be constructed, which were virtually defenseless and would have been better off had they never been built. In addition to all this, the passionate hater of war who hated alliances which entangled nations together, Jefferson proposed to make an alliance with England, then an enemy, against France, a long-time ally, with the object of waging a defensive war against France on American soil. The Republican party also favored small government, with little power given to the federal government, especially the President. Jefferson broke away from these beliefs also by his purchase of Louisiana from Spain. Nowhere in the Constitution, which he followed passionately, was there anything that gave the President the authorization to negotiate treaties, especially when it involved doubling the size of the union and allowing 50,000 non-Americans to live on this newly acquired land. Since his conscience bothered him, Jefferson secretly proposed an amendment to the Constitution which would grant him more power. This amendment failed, however, and he was forced to let the country know that his actions were unconstitutional. This change of ideals actually helped Jefferson to become re-elected. He breezed through the election of 1804, winning 162 electoral votes, as opposed to the 14 gained by his Federalist opponent. It was not that he imposed his Republican ideas on the Federalists, but that he did exactly the opposite. Jefferson actually was elected as Republican president, but he adopted many Federalist principles and embraced them as his own. This is how the most bipartisan President in history was able to come to power in one of the most bitterly partisan periods in America's history. American History Essays

Free Essays on Why Americans Dont Vote

The acquisition of political rights- including voting rights- has been a vital tool for every disempowered group in American’s history to achieve economic, social and civil rights and equality (Williamson, 1960; Porter, 1971). Because legislative bodies confer rights and make public policy, it is critical to possess the capacity to influence and/or select representatives. Legal barriers to political participation, however, have hampered the attainment of such rights by distinct classes of citizens, including African-Americans, women, and youth. Previously excluded groups have gained access to the franchise principally through political struggle. They fought their way into the polity through political agitation, sometimes using the courts as a tool. Ultimately they needed the support of other sectors in society to win political rights. The agitation of the property-less encouraged sectors of the propertied to extend the franchise; the abolitionist movement and civil rights movements led whites to enfranchise blacks; the suffragettes compelled men to include women among the voting citizenry; and younger adults, whose participation in the social movements of the 1960s and 1970s, were granted voting rights by older adults. Why not for immigrants too? Although noncitizen immigrants behave in much the same ways as citizens, they possess fewer rights and benefits.1 Immigrants are subject to all laws and pay taxes, work in and/or own businesses, send their children to schools, serve in the military and can be drafted, and participate in all aspects of daily social life. Nevertheless, noncitizen immigrants are precluded from selecting those who fashion public policy and represent them at every level of governance.

Employee referral campaigns Essay Example | Topics and Well Written Essays - 500 words

Employee referral campaigns - Essay Example Another advantage of employee referral campaigns is that they help promote the brand value of a company through word-of-mouth publicity. In order for an existing employee to bring his contacts into the company, he/she must first have a positive perception about the status and worthiness of the company. On the flip side, a poor response to an employee referral campaign can usually indicate an unmotivated workforce perceiving no incentive either for themselves or for their contacts in availing job opportunities with the company. One other obvious advantage of an ERC is that it cuts down recruitment related expenditure by eliminating the need for advertising, job fairs, hiring agencies, etc. In certain domains, highly specialized positions are best filled through personal channels and not through traditional recuitment processes, making a case for ERCs. On the negative side, employee referral campaigns can also create conflict-of-interest scenarios for the management, when they make an assessment that is inconsistent with that of the referring employee's. For example, a candidate being recommended by an employee could be estimated to be either unsuitable or unqualified for the vacant position. In such a case, the management usually ends up causing disappointment for both parties by declining to hire.
