To Investigate the Effect of Surface Area on the Rate of Reaction Using the Enzyme Catalase, Found in Potato, and the Substrate Hydrogen Peroxide

Hydrogen peroxide has an acidic pH which will break down into water which has a neutral pH. This may effect the enzyme action as many enzymes work faster in a neutral environment, the only control over this is the fact that it will happen in each test and to consider its effect at the end of the experiment. I will need to use the same potato and cut a fresh chip at each stage of the experiment as the catalase may become effected by exposure to the air. This may effect results so I will keep the chips as similar as possible. …
