When hydrogen peroxide is mixed with liquid soap and catalyst potassium iodide is added, a foamy substance is formed by the rapid decomposition of hydrogen peroxide. Name the experiment.
Elephant's Toothpaste Experiment
Hydrogen peroxide is first mixed with liquid soap. Then a catalyst, often potassium iodide, is added to make the hydrogen peroxide decompose very quickly. Hydrogen peroxide breaks down into oxygen and water. As a small amount of hydrogen peroxide generates a large volume of oxygen, the oxygen quickly pushes out of the container. The soapy water traps the oxygen, creating bubbles, and turns into foam. This experiment is called Elephant's Toothpaste Experiment.
