Empty vials were obtained and labeled one to three. 3 ml of hydrogen peroxide were distributed into each of the vials. A drop of liquid soap was then added to each of the bottles. The contents of the vials were gently shaken to ensure mixing of the hydrogen peroxide and soap. To each vial, pH buffer was added; Bottle one received pH 2 buffer, bottle two received pH 7 buffer, and bottle three received pH 12 buffer. 1 ml of catalase was then placed in each bottle and the reaction was timed for 2 minutes . After two minutes, the column of bubbles produced was measured and recorded in Table 3. The results were then graphed, as shown in Figure
