The balanced half-reaction equation is [tex]MnO_4^- + 4H^+ --- > MnO_2 + 2H_2O + 3e^-[/tex]
The term redox reaction has to do with a reaction in which there is a loss or gain of electrons. In this reaction, one specie accepts electrons while another species loses electrons.
The balanced half-reaction equation in acid is;
[tex]MnO_4^- + 4H^+ --- > MnO_2 + 2H_2O + 3e^-[/tex]
