Elephant toothpaste reaction Two people watching the reaction of Elephant's toothpaste. Elephant's toothpaste is a foamy substance caused by the quick decomposition of hydrogen peroxide (H 2 O 2) using potassium iodide (KI) or yeast and warm water as a catalyst. [1] How rapidly the reaction proceeds will depend on the concentration of hydrogen ...
Hydrogen peroxide solution and liquid detergent are carefully mixed in a beaker and transferred to a large cylinder. A saturated solution of potassium iodide (KI) is added to the cylinder. At the very contact of the solutions, a large amount of steaming foam (exothermic reaction) is formed resembling a giant toothpaste ('elephant toothpaste').

"About 50 ml of concentrated (>12%)[5] hydrogen peroxide is first mixed with liquid soap or dishwashing detergent. Then, a catalyst, often around 10 ml potassium iodide" How much foam will be produced from the amounts said in the wiki which i copy-pasted here? 77.75.244.130 14:03, 24 March 2022 (UTC)
These included static electricity, Alka-Seltzer rockets, elephant toothpaste and more. David Lu with Bayer says interactive events like this help students to learn better and build interest.

It can also be obtained by reacting bismuth nitrate pentahydrate and potassium iodide in ethylene glycol at 160 °C in a reactor. [3] The aqueous solution of bismuth nitrate acidified with nitric acid is adjusted by sodium hydroxide and then added dropwise with potassium iodide to obtain the reaction product, and other proportions of oxyiodides ...
