D\u00e8s que la solution aqueuse de permanganate de potassium est contenue dans un milieu acide, le permanganate violet est r\u00e9duit en cation incolore Mn+2. Dans les solutions neutres, le permanganate est r\u00e9duit \u00e0 MnO2, cation +4, ce qui donne un pr\u00e9cipit\u00e9 brun. Enfin dans les solutions alcalines ou basiques, il est r\u00e9duit \u00e0 son \u00e9tat +7, donnant KMnO4, avec la couleur violette avec laquelle le permanganate de potassium est connu<\/li>\n<li>Il a \u00e9galement des propri\u00e9t\u00e9s d\u00e9sinfectantes et d\u00e9odorantes.

En outre, il peut \u00eatre administr\u00e9 comme rem\u00e8de \u00e0 certaines intoxications avec des poisons oxydables comme le phosphore \u00e9l\u00e9mentaire ou les morsures de serpents.<\/li>\n<li>Une application courante se trouve dans le traitement de l\u2019eau potable.
