Catalytic Decomposition of Hydrogen Peroxide Materials 1 Liter Graduated Cylinder Large Watch Glass Large Tray (for Under Graduated Cylinder) Benchcote (or Other Plastic Backed Absorbant Paper) Gloves and Goggles 3 Solutions: A: 50ml 30% Hydrogen Peroxide (H2O2) (premeasured) B: Liquid Dish Soap C: 1gm KI (premeausured) Procedure 1. On a large sheet of plastic backed absorbent paper, place a 1 liter graduated cylinder on a tray or large petrie dish. 2. Add 50 mL 30% Hydrogen Peroxide and 4 drops of dish soap to the graduated cylinder. 3. When ready, add 1gm KI. Oxygen released by the rapidly catalyzed decomposition generates a tremendous amount of foam. Caution. This reaction generates a lot of heat. Glassware may burn your hand. Reactions H2O2 (aq) + I- (aq) --> H2O (l) + OI- (aq)
