A permanganate is a chemical compound that contains the permanganate ion (MnO4-). Because manganese is in the +7 oxidation state, the permanganate ion is a strong oxidizer. Permanganates are salts of permanganic acid. Permanganate is a strong oxidizer, and similar to perchlorate. Being a strong oxidizer it is in common use in qualitative analysis experiments involving redox reactions (permanganometry).
