WebI. The oxidative property of the permanganate ion Permanganate ion (MnO 4-) is a strong oxidizing agent. In acidic solution, it undergoes reduction to give manganese(II) ions … WebMore recently, permanganate has been used as an oxidant to treat contaminated soil and groundwater. When permanganate reacts with organic contaminants, the contaminants are oxidized to carbon dioxide and the permanganate is reduced to a manganese dioxide salt and a potassium (or sodium) salt.
