Sodium permanganate is the inorganic chemical compound NaMnO₄. In this salt, manganese is in the +7 oxidation state. The salt is also known as "permanganate of sodium". The permanganate ion is a strong oxidizing agent. It dissolves in water to give deep purple solutions, evaporation of which gives prismatic purple-black glistening crystals. It has a sweet taste and is odourless. A chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition. ...

Sodium permanganate has essentially the same properties and use as potassium permanganate and can be used as its direct substitute. Though it is more soluble, its hygroscopic nature reduces its stability and hence its effficacy as a primary standard. Thus potassium permanganate is used more extensively in the laboratory than its sodium counterpart. Potassium permanganate is the chemical compound KMnO4. ... A hygroscopic substance is a substance that absorbs water readily from its surroundings. ... The word standard has several meanings: Classically, standard referred to a flag or banner; especially, a national or other ensign carried into battle; thus standard bearer indicates the one who bears, or carries, the standard. ...
