Balancing Redox Equations in Acidic or Basic Solutions In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods. The oxidation number method balances the net increase in oxidation of the substance oxidized with the net decrease in the oxidation number of the substance reduced. The half-reaction method balances the electrons lost in the...
