Catalyst mass and volume of gas produced in decomposition of Hydrogen Peroxide


Equipment

Powdered catalyst
Hydrogen peroxide
250ml measuring cylinder
Washing up liquid
Top pan balance

Method

Add 50ml of Hydrogen Peroxide to the measuring cylinder and 5ml of washing up liquid.
Drop in 0.1g of the catalyst and measure the maximum height of the bubbles produced.
Repeat for different masses of catalyst.

Risks

Goggles should be worn at all times. Using too much catalyst may result in the foam overflowing the measuring cylinder so a supply of paper towels should be kept ready to clear up any spills.
