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 ...
English: Experiment known as 'elephant toothpaste'. 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 ...

To this a solution containing potassium iodide, sodium thiosulfate, and starch is added. There are two reactions occurring simultaneously in the solution. In the first, slow reaction, iodine is produced: H 2 O 2 + 2 I − + 2 H + → I 2 + 2 H 2 O. In the second, fast reaction, iodine is reconverted to two iodide ions by the thiosulfate:
For example, in the molecules represented by CH 3 X, where X is a halide, the carbon-X bonds have strengths, or bond dissociation energies, of 115, 83.7, 72.1, and 57.6 kcal/mol for X = fluoride, chloride, bromide, and iodide, respectively. [2] Of the halides, iodide usually is the best leaving group.
