Potassium permanganate to potassium manganate (oxidation state +6) and manganese dioxide (oxidation state +4). Oxygen gas is also liberated. Potassium permanganate poses risks as an oxidizer. Contact with skin will result in a long lasting pinkish/purple stain. Potassium permanganate Potassium permanganate is an inorganic chemical compound and medication. As a medication it is used for cleaning wounds and dermatitis. It has the chemical formula KMnO and is a salt consisting of K and ions. It is a strong oxidizing agent. It dissolves in water to give intensely pink or purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals. In 2000,
Potassium humate Potassium humate Potassium humate is the potassium salt of humic acid. It is manufactured commercially by alkaline extraction of brown coal (lignite) Leonardite to be used mainly as a soil conditioner. The extraction is performed in water with the addition of potassium hydroxide (KOH), sequestering agents and hydrotropic surfactants. Heat is used to increase the solubility of humic acids and hence more potassium humate can be extracted. The resulting liquid is dried to produce the amorphous crystalline like product which can then be added as a granule to fertiliser. The potassium humate granules by way of chemical extraction lose their
