Aim: To investigate the action of the enzyme catalyse Hydrogen Peroxide Water + Oxygen 2 H2 02 2H2 0 + 02 Hydrogen peroxide is a poisonous waste product in chemical reactions. Catalyse converts it to water and oxygen rapidly. Factors affecting reaction P.H Concentration of Hydrogen Peroxide Temperature Concentration of catalyze in potato Prediction I think that the greater the surface area of catalyst the faster the reaction will occur, this is because there is more chance of the molecules colliding with each other because there are more enzymes and...
get a bung that sealed so it was all right. Instead of trying to use a conical flask, we could have used a gas syringe to collect the oxygen in. This would be more accurate because there is less chance of losing any oxygen, because it is a direct connection and unlikely to leak or move out of position. If we had more time we could of done some further experiments like, Using different potatoes, changing the concentration of the hydrogen peroxide, or changing the temperature the experiment was done at enzymes work best at 30 to 40c.

Prediction I predict that the higher the concentration of salt, the lower the mass the potato cylinder will become. This is because there is a greater concentration of water molecules inside the potato cylinder, so the water will drain from the cylinder by osmosis, to where there was a...

The American Cancer Society estimates that 18,300 Americans will be diagnosed with malignant brain, spinal cord and other nervous system tumors in 2003. Approximately 13,100 people in the United States will die from brain, spinal cord, and other nervous system tumors in 2003. Brain and spinal cord tumors occur most...
