Investigating the breakdown of hydrogen peroxide to oxygen and water by catalase enzyme. AIM To investigate the how increasing the mass of potato [and therefore the amount of catalase enzyme] effects the volume of oxygen produced. There are a few variables: * The concentration of hydrogen peroxide. * The volume hydrogen peroxide. * The amount of catalase which is in the cubes of potato. * The surface area of the potato. * The temperature at which the reaction takes place. These are variables because: * If you increase the concentration of hydrogen peroxide, there are more H2O2 molecules per cm3. Therefore there is a greater oxygen content, so more oxygen will be produced. * If you increase the volume of hydrogen peroxide, then more oxygen will be produced by complete decomposition because there are more O2 molecules in the solution. * Increasing the amount of catalase means that the reaction will go faster. The yield of oxygen will not...
