Hydrocinnamic acid underwent bromination using N-bromosuccinimide and AIBN. As one lab partner set up the reflux apparatus‚ the other measured the chemicals used in the lab experiment. 2.10 g of hydrocinnamic acid was used. It was observed as white and had a slight cinnamon smell. The amount of NBS was 2.49g and was measured in the fume hood. AIBN was measured at .030 g. 10 mL of acetic acid was also obtained. The reflux apparatus consisted of a 25 mL flask with a stir bar in a water bath. The chemicals

Abstract Our study is entitled “The Feasibility of Aspartic Acid found in Oyster Shells as an additive ingredient in improving the absorbency of commercialized sanitary napkins.” The objective of the study was to extract a protein from the oyster shells to produce aspartic acid which can replace the manufactured polymer found in commercialized sanitary napkins. The significance of our study is that the product is an alternative in producing polymers. It is also environmental friendly; biodegradable

Preparing Esters by esterification method using carboxylic acid to an alcohol‚ which is 1.0 ml of ethanoic acid to the ethanol‚ and ethanoic acid to the propan-1-ol‚ also adding H2SO4 as a catalyst for the reaction Abstract: Esters are a group of organic compound‚ famous for their interesting odours and smells. In this investigation student used ethanoic acid and ethanol with sulfuric acid as catalyst to produce ester‚ which was known of its smell. However it was expected to have a pleasant smell

Introduction Background Information To begin a discussion about acid-base titrations‚ we must first recall that there are several definitions of acids and bases. For the purpose of this exercise‚ we will consider the Arrhenius definition of acids and bases‚ in which an acid is a proton (H+) donor and a base produces hydroxide (OH-) in solution. When an acid reacts with a base‚ the products of this reaction are water and a salt. Note that salt here does not only mean table salt (NaCl)‚ but can refer

The objective of this lab was to. First‚ we measured out 2.00g of granular zinc and 2.03g of iodine crystals and added them together into a boiling tube‚ which we labeled "R". After‚ we added a boiling chip into a large test tube labeled "P" and we also labeled an empty regular sized test tube with a "C". When we added 5mL of acetic acid to tube R‚ the solution turned red and was hot. After we add 30 drops of the red solution into tube C and continued to swirl tube R‚ the solution became

The Role of the Citric Acid Cycle The Citric Acid Cycle is a series of enzyme-catalysed reactions that take place in the mitochondrial matrix of all aerobic organisms. It involves the oxidation of the acetyl group of acetyl CoA to two molecules of carbon dioxide. Each cycle produces one molecule of ATP by substrate-level phosphorylation‚ and reduces three molecules of NAD and one molecule of FAD for use in Oxidative Phosphorylation. The cycle is preceded by Glycolysis‚ which also occurs in anaerobic
