WebThe oxidation state of Mn in MnO4- is +7. The following calculation gives this result: Let oxidation state of Mn be x. Therefore, x+4 (-2)=-1 because oxidation state of oxygen is-2 and overall the ion has unit negative charge. Solving the above equation, you will get x=+7. Permanganates(VII) are salts of permanganic acid. They have a deep purple colour, due to a charge transfer transition from oxo ligand p orbitals to empty orbitals derived from manganese(VII) d orbitals. Permanganate(VII) is a strong oxidizer, and similar to perchlorate. It is therefore in common use in qualitative analysis that involves redox reactions (permanganometry). According to theory, permanganate is strong enough to oxidize water, but this does not actually happen to …
