In an acidic solution, permanganate(VII) is reduced to the pale pink manganese(II) (Mn 2+) with an oxidation state of +2. 8 H + + MnO − 4 + 5 e − → Mn 2+ + 4 H 2 O. In a strongly basic or alkaline solution, permanganate(VII) is reduced to the green manganate ion, MnO 2− 4 with an oxidation state of +6. MnO − 4 + e − → MnO 2− 4

The most prominent example of Mn in the +6 oxidation state is the green anion manganate, [MnO 4] 2−. Manganate salts are intermediates in the extraction of manganese from its ores. Compounds with oxidation states +5 are somewhat elusive, and often found associated to an oxide (O 2−) or nitride (N 3−) ligand. [29]
4, also known as manganate(VI) because it contains manganese in the +6 oxidation state. [1] Manganates are the only known manganese(VI) compounds. [2] Other manganates include hypomanganate or manganate(V), MnO 3− 4, permanganate or manganate(VII), MnO − 4, and the dimanganate or dimanganate(III) Mn 2 O 6− 6. A manganate(IV) anion MnO 4−
By removing ethylene by oxidation, the permanganate delays the ripening, increasing the fruit's shelf life up to 4 weeks without the need for refrigeration. [ 52 ] [ 53 ] [ 54 ] The chemical reaction, in which ethylene (C 2 H 4 ) is oxidised by potassium permanganate (KMnO 4 ) to carbon dioxide (CO 2 ), manganese oxide (MnO 2 ) and potassium ...

Sodium permanganate is the inorganic compound with the formula Na MnO 4.It is closely related to the more commonly encountered potassium permanganate, but it is generally less desirable, because it is more expensive to produce.
