Abstract (Introduction). Purpose: Determine if adding more catalase to a beaker of hydrogen peroxide would produce more oxygen gas. Experiment Summary: We used gas pressure sensor to measure the amount of gas that was given off during the reaction in three different trials. . Makenzie Nelson. Alexis . Beyke. Lily Harvey. Experiment. An experiment was conducted to determine how the concentration of catalase affects a solution of H2O2.. One trial was run on each of the three different concentrations of catalase..
