Potassium Permanganate 98.5+% Pure

Potassium permanganate is an anhydrous, solid, ionic chemical compound of potassium K+ ions and MnO4 permanganate ions with the chemical formula KMnO4. The manganese atoms are in oxidation state +VII, so the name according to IUPAC is potassium manganate (VII). Being highly soluble in water, it is an important salt in inorganic chemistry, especially in manganimetry or analytical determination by the permanganate ion.

Potassium permanganate KMnO4 is a powerful oxidizing agent. In the solid state, it appears as purple crystals with a metallic sheen.

It decomposes thermally at 240°C into manganese dioxide and oxygen gas.

The aqueous solution, which is highly soluble in water, is purple in color and increases in intensity with concentration.

Solid potassium permanganate is a very strong oxidizing agent. A very exothermic reaction occurs when mixed with glycerin. This can result in spontaneous combustion which can melt glass and a large number of containers and ignite any combustible materials in the vicinity. This type of reaction can occur when solid potassium permanganate KMnO4 is contacted with a large number of organic compounds. Aqueous solutions of KMnO4, and especially dilute solutions, are much less dangerous. Potassium permanganate should never be stored near petroleum or any easily oxidizable substance.

Potassium permanganate can stain clothing or skin, it reacts with skin or fabric, similar to reducing bodies for this oxidizing body, and leaves traces of manganese dioxide, causing brown or brown spots on the skin. More seriously, it gnaws deeply at the contaminated mucous membranes and walls of the digestive tract to the stomach if accidentally ingested. This substance and its fresh aqueous solutions should be handled with care. Stains on clothing can be cleaned with iron(II) sulphate or oxalic acid. The spots on the skin disappear after about 3 weeks or even 1 month and in some cases even more. Nail stains can be removed with oxalic acid.
