Catalytic Decomposition of Hydrogen Peroxide H2O2 – Elephant’s Toothpaste Experiment
Elephant’s toothpaste is a foamy substance, formed as a result of rapid decomposition of hydrogen peroxide. Elephant’s toothpaste is a chemical reaction experiment. This experiment is generally used for classroom demonstrations, as it requires fewer ingredients and makes a “volcano of foam”.
