Investigation on the effects of Temperature‚ pH levels‚ and Enzyme Concentration on the reaction rate of the Decomposition of Hydrogen Peroxide by Catalase The purpose of this investigation is to figure out how temperature‚ pH‚ and enzyme concentration affect the reaction rate of an enzyme. It’s important to understand how certain factors affect enzymes because of their crucial role in the metabolic processes of life. Enzymes lower the activation energy necessary for a chemical reaction to

Technology Organic Chemistry Laboratory ABSTRACT Recrystallization is one of the simplest and most widely used technique for purifying organic solids through the differences in solubility at different temperatures. It is also the process in which the solid to be crystallized is dissolved to either a hot solvent or a hot solvent mixture and is cooled in a solution.In this experiment‚ acetanilide‚ the crude product of acetylation of aniline and acetic anhydride‚ was used as the pure organic compound

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

Chemical Aspects of Life and Spit Lab Formal Report 1. Abstract The objective of the Reducing Sugar Test was to test if the substance has a reducing sugar in it by adding Benedict’s solution and heating it‚ there would be a color change if a reducing sugar is present‚ or it will remain blue (no reducing sugar). The objective of the Starch test was to test for starch in substances by using Iodine. The iodine will cause a substance to turn to a dark blue color if it is positive for starch. The objective
