Explanation

Potassium permanganate is an inorganic chemical compound with the formula KMnO4. Formerly known as permanganate of potash or Condy's crystals, it is a strong oxidizing agent. It dissolves in water to give intensely purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals.
