Calcium permanganate is an oxidizing agent and chemical compound with the chemical formula Ca(MnO4)2. This salt consists of the metal calcium and two permanganate ions.
Preparation
The salt is prepared from the reaction of potassium permanganate with calcium chloride[2] or from the reaction of aluminium permanganate with calcium oxide. It can also be prepared by reacting manganese dioxide with a solution of calcium hypochlorite and a little bit of calcium hydroxide to increase the pH level.[citation needed]
Uses
Calcium permanganate is used in the textile industry, for sterilization of water, and as a
Safety
It is noncombustible, but being a strong oxidizing agent, it will accelerate the burning of combustible material. If the combustible material is finely divided, the resulting mixture may be explosive. Contact with liquid combustible materials may result in spontaneous ignition. Contact with
