Potassium permanganate

A solution of KMnO4 in water, in a volumetric flask

Crystallization of KMnO4 aqueous solution in real-time due to evaporation, 200x magnification

Potassium permanganate is an inorganic chemical compound with the chemical formula KMnO₄. It is a salt consisting of K and MnO−
4 ions. Formerly known as permanganate of potash or Condy's crystals, 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, worldwide production was estimated at 30,000 tonnes. In this compound, manganese is in the +7 oxidation state.
