The Science behind 3 H2O2 Elephant Toothpaste

At its core, 3 H2O2 elephant toothpaste is a demonstration of the rapid decomposition of hydrogen peroxide (H2O2) when mixed with a catalyst like potassium iodide (KI). When these two ingredients combine, a chemical reaction occurs, resulting in the release of oxygen gas and water. The dish soap added to the mixture acts as a surfactant, trapping the oxygen gas and creating the foamy eruption we associate with elephant toothpaste.

The decomposition of hydrogen peroxide can be represented by the following equation:

2 H2O2 → 2 H2O + O2

The addition of potassium iodide as a catalyst speeds up the reaction, making it even more explosive. The catalyst provides an alternative pathway for the decomposition of hydrogen peroxide, allowing it to occur more quickly and efficiently.
