The half-reaction below is proposed for basic solution: SO32−+2 H2O  →  SO42−+H2+2 e−\mathrm{SO_3^{2-} + 2\,H_2O \;\rightarrow\; SO_4^{2-} + H_2 + 2\,e^-} Calculate the total charge on each side of the equation and indicate whether additional electrons should be placed on the reactant side or on the product side to achieve charge balance.
