Potassium permanganate is an inorganic compound with the chemical formula KMnO 4.It is a purplish-black crystalline salt, which dissolves in water as K + and MnO − 4 ions to give an intensely pink to purple solution.
This green color results from an intense absorption at 610 nm. In the laboratory, K 2 MnO 4 can be synthesized by heating a solution of KMnO 4 in concentrated KOH solution followed by cooling to give green crystals: [3] 4 KMnO 4 + 4 KOH → 4 K 2 MnO 4 + O 2 + 2 H 2 O. This reaction illustrates the relatively rare role of hydroxide as a ...

Potassium permanganate (KMnO 4) is a dark violet colored powder. Its reaction with glycerol (commonly known as glycerin or glycerine) (C 3 H 5 (OH) 3) is highly exothermic, resulting rapidly in a flame, along with the formation of carbon dioxide and water vapour:
Stock nomenclature for inorganic compounds is a widely used system of chemical nomenclature developed by the German chemist Alfred Stock and first published in 1919. In the "Stock system", the oxidation states of some or all of the elements in a compound are indicated in parentheses by Roman numerals .
