The permanganate ion MnO-4 can be reduced to the manganese( II) ion Mn2+ in aqueous acidic solution, and the reduction potential for this half-cell reaction is 1.52 V. If this half-cell is combined with a Zn2+|Zn half-cell to form a galvanic cell at standard conditions,
(a) Write the chemical equation for the half-reaction occurring at the anode.
(b) Write the chemical equation for the half-reaction occurring at the cathode.
(c) Write the overall balanced equation for the reaction.
