High Quality Content by WIKIPEDIA articles! 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. The ion has a tetrahedral geometry. Permanganate solutions are purple in color and are stable in neutral or slightly alkaline media.Permanganates(VII) are salts of permanganic acid. Permanganate(VII) is a strong oxidizer, and similar to perchlorate. It is therefore in common use in qualitative analysis that involves redox reactions (permanganometry). Besides this, it is stable.It is a useful reagent, though with organic compounds, not very selective.
