Abstract In this experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as

STANDARDIATION OF ACID AND BASE Eunice Ivy B. Gamboa ABSTRACT Solutions of known concentration are prepared by dissolving measured masses of standard acids in distilled water. The concentrations of unknown solutions of sodium hydroxide are determined by titration. An acid solution reacts with a base solution in a "neutralization" reaction. Titrations permit the concentrations of unknown acids/bases to be determined with a high degree of accuracy. In order to analyze unknown acids/bases‚ we must have

the Mango Rains Monique and the mango rains is a touching story about a peace corps volunteer and a Malian midwife. The story is set in the small village of Namposella and is narrated by the Peace Corps volunteer Kris Holloway. The book gives you an in depth perspective on the life of a woman in Mali and their culture as a whole. In this paper I will be discussing anthropological concepts including rite of passage‚ patriarchy‚ and religion and how they apply to Monique and the mango rains. Religion

In the novel Year of No Rain they have many problems in Sudan they have good things then they have really bad things that happen to them. JUBA‚ South Sudan — For nearly two weeks‚ they have hunkered in a schoolyard with nothing to do and nowhere else to go‚ dozens of people battling hunger‚ swarms of mosquitoes — and fear. Is There Any Hope for Peace in South Sudan? On average‚ about 2‚500 refugees — mostly women and children — are crossing from South Sudan into Uganda every day. Many are living

Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed

impacts on the overall society. John Foulcher depicts the idea of the lack of connection of our society with the Mother Nature and with others through his poem “Summer Rain”. Not only this he also indicates that we are not only blowing the humanity away but also condemning nature. Foulcher starts his poem with an ironic topic ‘Summer Rain’ which usually sets up expectations of nature‚ joy‚ cleansing and beauty but instead we see disconnection from nature‚ traffic jam and pollution. Our society plays

Analysis of Antacid Tablets I. Introduction An acid-base titration is a method of neutralizing strong acids. Unbeknownst to many‚ acid-base titrations occur on a daily basis. Our stomachs use acid to help us digest our food – approximately .155 hydrochloric acid (HCl) with a pH of 2-3. When too much of this acid is formed in the stomach‚ heartburn and other discomfort occurs. This is when people grab for their antacids; these are bases that neutralize the excess acid in the

Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus
