Elephant toothpaste reaction rate
About 50 ml of concentrated (>12%) hydrogen peroxide is first mixed with liquid soap or dishwashing detergent. Then, a catalyst, often around 10 ml potassium iodide solution or catalase from baker's yeast, 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 volum… WebHow does elephant toothpaste work? When you mix yeast into hydrogen peroxide, the hydrogen peroxide breaks down rapidly into a large amount of oxygen and water. This causes the mixture to expand at a speedy rate and explode out of the bottle. The added washing-up liquid turns it into a foam by trapping the oxygen bubbles.
