At the beginning of the lab‚ a micro test tube with and without glass wool was weighed on an analytical balance. A watch glass‚ crucible‚ and lid were also weighed. The masses of all the materials needed for the lab were recorded in the data tables of the laboratory notebook. An unknown vial was obtained from the teacher and set to zero on the balance. About 0.6 grams of the unknown was measured into the micro test tube. The analytical balance was set to zero again and then the test tube with the

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

Distinguished ladies and gentlemen. Acid rain is becoming a widespread problem around the world. The amount of acid in rain has dramatically increased in the past decade in certain areas like America and Europe by 70%. How is it caused? It is formed by the chemicals in the process of burning fossil fuels mixing with the moisture in the Earth’s atmosphere. Acid rain come in two forms‚ wet and dry. Dry deposition‚ a more accurate term for acid rain‚ can appear to be snow‚ hail or other dry particles

Amino acids are important building blocks; they play an essential role in the formation of proteins and as intermediates in metabolism. Amino acids can serve as cell signaling molecules and can regulate gene expression. An optimal amount of amino acids is essential for health. There are over 500 amino acids‚ however only 20 are commonly found. Amino acids all have an amine functional group and a carboxylic acid functional group. They differentiate from each other in their side chains. Only 10 of

Introduction: The theory behind the extraction of a solution containing benzoic acid‚ cellulose‚ and methyl orange involves many components pertaining to the fundamental ideas of solubility and polarity. Using the concepts of like dissolving like and acid base reactions‚ a solution of organic acid (benzoic acid)‚ a water soluble compound cellulose‚ and an organic soluble compound methyl orange‚ can be separated and benzoic acid can be isolated by a method of extraction. At the fundamental level‚

CHEMICAL REACTIONS: ACID-BASE BUFFERS Short Overview Acids and bases represent two of the most common classes of compounds. Many studies have been done on these compounds‚ and their reactions are very important. Perhaps the most important reaction is the one in which an acid and base are combined‚ resulting in the formation of water (in aqueous solution) and a salt; this reaction is called neutralization. A buffer solution is a solution that contains both an acid and a salt containing
