Sodium Permanganate

Sodium permanganate is an inorganic compound in the form of a purple, odourless, oxidizing solid. It can be prepared by the reaction of manganese dioxide with sodium hypochlorite. Sodium Permanganate dissolves readily in water to give deep purple solutions. Due to safer handling Sodium Permanganate is commercially supplied in a liquid form, usually at a concentration of around 40%.
