Hydrogen Peroxide

A detailed Summary of Hydrogen Peroxide


An investigation into how the amount of oxygen is produced by changing one variable effects the decomposition of Hydrogen Peroxide in the presence of the enzyme.

This shows us that when the H2O2 has reacted with the catalyst this is what it produces.

There are many ways in which the amount of oxygen produced could be affected. I believe that, surface area of the chip, temperature of liquid that is reacting, the concentration of the liquid or the amount used are going to be the major variables in the experiment.

From these variables I clearly believe that looking at the concentration of the liquid, in this case H2O2, will be the best experiment to do. Also I believe that this will give us a strong set of results with which we will be able to pull good clear conclusions from.

To keep all other variables constant so they do not influence my results, we will do all experiments in the same room hopefully the temperature remains constant in that one room, all potato chips will be cut with a size 4 cork bora and then cut into 3 centimetres, as to keep each test fair. Also the volume of the concentration H2O2 will remai


This shallower line almost horizontal shows that it is finding it hard to produce a lot of oxygen because there are not enough molecules for the enzymes to react with. To get an even bigger picture of this experiment we know that our 100% is 10ml3 of H2O2 so if we increase this to 110% we will have 11ml3 of H2O2 therefore exposing more molecules to the enzymes. This would increase our results and give us a more detailed graph.

This a diagram of how my experiment is set up:
