Potato And Hydrogen Peroxide Experiment. Feb 01 2022 0213 PM. If potatoes are used as a peroxidase in the hydrogen peroxide solution they will generate more oxygen than if apples are used because potatoes contain more catalase and when catalase is added to hydrogen peroxide there is an initial rapid evolution of oxygen.
