    In the reaction mechanism‚ the alpha hydroxyketone’s hydroxylic group attacks the positively charged nitrogen from nitric acid attaching it to the molecule. The nitrogen’s electrons are then kicked off on to the oxygen bearing a positive charge‚ creating water. This process formed an organic nitrate. Next‚ water is used to abstract hydrogen from the positively charged oxygen‚ forming hydronium. A carbonyl is formed as well as nitrogen dioxide gas. Simultaneously the oxygen separates itself from nitrogen

    Laboratory Exercise #3 Measuring Protein in Solution Abstract The purpose of this lab was to learn about the Biuret assay reaction to determine if it can detect proteins and amino acids; also‚ to understand the process of “salting out” proteins and how to determine the amount of protein in a solution. In order to do so‚ egg white and ammonium sulfate were mixed on ice and then put into the centrifuge. After PBS was added‚ the amount of protein could then be determined. After that‚ 14 test tubes

    of an object is determined using a process called titration. According to Petrucci et al.‚ titration is a reaction carried out by the carefully controlled addition of one solution to another. It has several types like acid-base titrations and redox titrations. This experiment focuses on the latter type‚ the redox titration. A redox titration is based on an oxidation-reduction reaction between analyte and titrant (Harris‚2009). It involves the transfer of electrons between the two solutions. This

    165mL acetic anhydride and a magnetic spin vane. An air condenser was attached to the vial and it was heated on an aluminum block‚ with a temperature maintained at 120C. After the solution dissolved‚ it was heated an extra 20 minutes to allow the reaction to go to completion then cooled back to room temperature. An ice bath was used to encourage crystal growth. The crystals were removed and centrifuged‚ then placed on a pre-weighed watch glass to dry and weigh. Percent recovery was found. A small
