1.PERMANGANATE A permanganate is the general name for a chemical compound containing the manganate(VII) ion, (MnO4−). Because manganese is in the +7 oxidation state, the manganate(VII) ion is a strong oxidizing agent.
In an acidic solution, manganate(VII) is reduced to the colourless +2 oxidation state of the Manganese(II) (Mn2+) ion.
8 H3O + + MnO4− + 5 e− → Mn2+ + 4 H2O
