Overview
Generally purplish colored. Soluble in water. Noncombustible, but accelerate the burning of combustible material. If the combustible material is finely divided, the mixture may be explosive. May spontaneously ignite in contact with liquid combustible materials. Contact with sulfuric acid may cause fire or explosion.

Reactivity Profile
Acetic acid or acetic anhydride can explode with permanganates if not kept cold, [Von Schwartz 1918. p. 34]. Explosions can occur when permanganates, treated with sulfuric acid come in contact with benzene, carbon disulfide, diethyl ether, ethyl alcohol, petroleum, or organic matter.
Air and Water ReactionsSoluble in water.
