Unformatted text preview: What’s My Name? CHEM 113 PURPOSE The purpose of this experiment is to determine the rate of reactions between hydrogen peroxide and potassium iodide with varying amounts of hydrogen peroxide and potassium iodide. This experiment will provide a better understanding of determining the rate law of any reactions given the proper solutions. Specifically the rate law for the reaction at low acidity will be determined in this experiment. A better understanding of the usage of an acetate-acetic acid buffer to keep acidity constant and low can come from this experiment. Also an understanding of the necessity of eliminating the reverse reactions to properly measure the initial rate can, in this case, be done with thiosulfate. PROCEDURES The first step is to prepare a solution with a 250ml beaker by adding all of the required components besides the hydrogen peroxide. In a separate beaker, a solution of hydrogen pperxide solution should be prepared. Then the time will be measured from the moment the two solutions are mixed until the uniform prepared....
