Potassium Permanganate Experiments
By Matthew Badger; Updated October 06, 2017

Potassium permanganate is a strong oxidizing agent. The standard industrial use of this compound is in water treatment for color removal, taste and odor control, and removal of iron and manganese. Potassium permanganate also inactivates certain viruses and bacterias. When combined with organic materials the reaction is explosive and leaves behind a permanganate residue.
Oxidation of Glycerin by Potassium Permanganate
This experiment demonstrates an exothermic release of energy in the form of heat from the ensuing reaction. The reaction involves the oxidation of glycerin by potassium permanganate. Glycerin is an organic compound and an easily oxidized substance.
You need about 20 grams of potassium permanganate powder, 3 to 5 milliliters of glycerin and a pipette. You also need a clean 70 milliliter beaker, glass tamping rod or test tube, and protective eye glasses.
In a well ventilated area, scoop the potassium permanganate into the beaker. Create an impression by tamping the substance with test tube or glass rod.
Using the pipette, quickly but carefully drop glycerin into the impression. As the glycerin is oxidized, it produces a bright flame as result of an exothermic reaction.
Potassium Permanganate Diffusion in Water
This experiment demonstrates the principle of chemical diffusion using potassium permanganate in water.
You need a a clean 70 milliliter beaker and a few potassium permanganate crystals.
Place the crystals at the bottom of the beaker. Steadily add distilled water to the beaker up to 35 milliliters or so of volume. Because of the random movement of potassium permanganate particles, a dense purple solution forms in water at base of the beaker. The purple solution will slowly spread into the rest of the water throughout the beaker creating a less dense but evenly colored purple solution.
