Abstract
The purpose of this experiment was to determine the effect of different aqueous solutions of ionic compounds on the rate of reaction of the enzyme catalase. The hypothesis states that zinc and cadmium acetate solutions will significantly inhibit catalase and its ability to produce oxygen. In the experiment, there were five trials performed with the lead acetate, zinc acetate, acetic acid, cadmium acetate, and distilled water (the last being the control group). In order to calculate the results, the ANOVA single factor test was used, comparing each solution to water. From results of the ANOVA test, it was found that the lead acetate, zinc acetate, and the acetic acid all significantly reduced the rate of reaction of the enzyme catalase, while cadmium acetate did not.
