Hydrogen Peroxide essays

Hydrogen Peroxide essays 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 remain at 10ml3 and the amount water that is placed into the measuring cylinder will also be 10ml3. To set-up this experiment will be quite tricky, as we have to place the bung into the water and up the measuring cylinder very quickly as to not loose any of the oxygen produced in the first few seconds. We will overcome this problem by paralysing the measuring cylinder with a clamp stand, and another to hold the boiling tube where the H2O2 and potato chip are; which contain the enzymes used to catalyse the H2O2 to help produce the oxygen a lot quicker. We used the water in the measuring cylinder to measure the overall amount of oxygen produced by seeing how much the oxygen had displaced. This a diagram of how my experiment is set up: 3 boiling tubes, 3 measuring cylinders, 3 wa...
