Potassium permanganate

It is an inorganic compound with the chemical formula KMnO4 and consists of K + and MnO−. It is a blackish-white crystalline salt that dissolves in water to give strongly pink or purple solutions and also appears as a purple crystalline solid.

Potassium permanganate is a common chemical compound that combines manganese oxide rock and potassium hydroxide. Potassium permanganate is an oxidizing agent with antiseptic, aromatic and astringent properties. It is sometimes called slow crystals by its common name. It is a non-combustible chemical but accelerates the combustion of combustible materials. If combustible materials are mixed well, the mixture can be explosive. Its contact with liquid combustible materials may lead to spontaneous combustion. Contact with sulfuric acid may cause fire or explosion. It is also used to make other chemicals and disinfectants. Potassium permanganate is widely used in the chemical industry and laboratories as a potent oxidant as well as as a medicine for dermatitis, wound cleansing and general disinfection. It is one of the safest and most effective drugs needed in a health care system in the WHO list of essential drugs.

Main applications of potassium permanganate:

Urban water treatment, wastewater treatment, synthesis of organic compounds, analytical use, medical uses, fruit preservation, survival kits, fire service, manufacturing and chemical processing, aquaculture, metal processing, air and gas treatment, filmmaking, agriculture

• In addition to the items mentioned as potassium permanganate
• Dyes and bleaches in the textile and tanning industries
• Oxidizer in radioactive waste disinfectant
• Auxiliary in flotation processes used in extraction
• In cleaning printed circuit boards

And is used in many other applications.
