Physical & Chemical Properties
| Melting Point | greater than 464 °F (USCG, 1999) |
| Density | 2.7 at 59 °F (USCG, 1999) - Denser than water; will sink |
| Solubility | Soluble in many organic solvents; also by concentrated acids with the liberation of oxygen. |
| Vapor Pressure | Vapor pressure at 20 °C: negligible |
| Appearance | Potassium permanganate appears as a purplish colored crystalline solid. Noncombustible but accelerates the burning of combustible material. If the combustible material is finely divided the mixture may be explosive. Contact with liquid combustible materials may result in spontaneous ignition. Contact with sulfuric acid may cause fire or explosion. Used to make other chemicals and as a disinfectant. |
