Ammonium permanganate is the chemical compound NH4MnO4, or NH3.HMnO4. It is soluble in water. It is a strong oxidizer, owing to its permanganate anion, and it is a moderately strong explosive, owing to the combination of oxidizer anion and reducing ammonium cation.

Calcium permanganate is an oxidizing agent. It consists of the metal calcium and two permanganate ions. It is noncombustible, but it will accelerate 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.

Potassium permanganate is the inorganic chemical compound with the formula KMnO4. It is a salt consisting of K+ and MnO4- ions. Formerly known as permanganate of potash or Condy's crystals, it is a strong oxidizing agent. It dissolves in water to give intense purple solutions, the evaporation of which gives prismatic purplish-black glistening crystals

Potassium permanganate is the inorganic chemical compound KMnO4, a water soluble salt consisting of equal mole amounts of potassium (K+) and permanganate (MnO4-, officially called manganate(VII) ) ions. This salt, formerly known as permanganate of potash or Condy's crystals is a strong oxidizing agent. It dissolves in water to give intense purple solutions, evaporation of which gives prismatic purplish-black glistening crystals

Sodium permanganate is the inorganic compound with the formula NaMnO4. It is closely related to the more commonly encountered potassium permanganate, but it is generally less desirable, because it is more expensive, absorbs water from the atmosphere, and low melting.
