Classical Idea Of Redox Reactions Oxidation And Reduction Reactions

The non-existence of and is probably due to the strong oxidizing power of ions and strong reducing power of and ions.

In neutral medium, potassium permanganate (KMnO ) oxidises manganese(II) salts such as manganese sulfate (MnSO ) to MnO . The reaction in neutral medium is: Here, KMnO acts as an oxidizing agent, and in neutral or slightly alkaline conditions, it reduces to MnO . The manganese in MnSO is in the +2 oxidation state, and it is oxidized to the +4 oxidation state in MnO .
Thus, the correct answer is MnO .
