permanganate

a salt of permanganic acid

permanganate [¦pər′maŋ·gə‚nāt]

(inorganic chemistry)

A purple salt of permanganic acid containing the MnO₄^-radical; used as an oxidizing agent and a disinfectant.

Permanganate

a salt of permanganic acid (HMnO₄). Permanganate crystals are nearly black, with a greenish violet hue, while permanganate solutions are usually tinted the red-violet color of the ion. Permanganates of sodium and bivalent metals dissolve freely in water, but KMnO₄ is only sparingly soluble. Permanganates are extremely unstable upon heating. For example, KMnO₄ decomposes at temperatures as low as 200°C according to the equation 2KMnO₄ = K₂MnO₄ + MnO₂+ O₂.

Permanganates are strong oxidizing agents, especially in an acid medium; thus, for example, Mn(VII) reduces to Mn(II), as in MnSO₄. Their use as oxidizing agents in chemistry is widespread, and in medicine permanganates are used as disinfectants and in the treatment of burns.
