Potassium Per Magnate
Potassium permanganate is an inorganic compound with the chemical formula KMnO4. It is a purplish-black crystalline salt, that dissolves in water as K+ and MnO−
4, an intensely pink to purple solution.
Potassium permanganate is widely used in the chemical industry and laboratories as a strong oxidizing agent, and also as a medication for dermatitis, for cleaning wounds, and general disinfection. It is on the World Health Organization’s List of Essential Medicines. In 2000, worldwide production was estimated at 30,000 tons.
Application
It is used as a anti-infective, germicide, bactericide, disinfectant and colorants
