How do we know pure oxygen and H2O is being released when liver is added to peroxide? In this experiment, we will find out how to test if pure oxygen is present when the enzymes in the liver break down the peroxide. By using water, peroxide, matches, and the liver, we will prove if the peroxide is broken down into pure oxygen and water.

- 5 test tubes
- 4 pieces of liver (one piece boiled)
