Tested Demonstrations
Demonstration of the Catalytic Decomposition of Hydrogen Peroxide
Alfred R. Conklin, Jr. and Angela Kessinger
Wilmington College, Wilmington, OH 45177
Cover
September 1996
Vol. 73 No. 9
p. 838
Abstract
Catalytic decomposition is demonstrated by placing hydrogen peroxide solutions in a one liter graduated cylinder and adding soap, food coloring, and potassium iodide. Released oxygen is trapped by the soap producing bubbles. The volume of bubbles is proportional to the concentration of hydrogen peroxide. Chloride and bromide do not cause decomposition. Increased reactant temperature increases the volume of bubbles formed.
