H2O2 H2O + O

To help us do this more quickly we have Enzymes. Catalase is the enzyme which allows this reaction to take place and is found in the liver. Other living materials also contain catalase, e.g. potatoes. These are cheaper and easier to hand and are useful for experiments.

I predict that the bigger surface area of the potato chip, the more bubbles of oxygen will be produced.

I think my prediction will be correct; one example of this happ

5. After the three minutes were up, I counted the number of oxygen produced by looking at the g1ass burette and checking how much hydrogen peroxide had been used up.
