SODIUM PERMANGANATE

Sodium permanganate is the inorganic compound with the formula NaMnO4. It is closely related to potassium permanganate and behaves similarly to potassium permanganate. It dissolves readily in water to give deep purple solutions, evaporation of which gives prismatic purple-black glistening crystals of the monohydrate NaMnO4·H2O.
