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 halffiacfion
method or the oxidation number method. The haifereaction
method balanoes the electrons lost in the oxidation haiffiacfion
with the elections gained in the reduction halfereaction. in either
method Hgoil). OH- (aq). and H+ (aq) may be added to
complete the mass balance. Which substances are used
depends on the reaction conditions. ACIGIC Sflillijfll’l In acidic solution, the nitrate ion can be used to react with a number ofmetal ions. One such reaction ‘3 N03 * (all) + 5,12. (am-mom) + Sn (aq)
Since this reaction takes place in acidic solution, H200) and H+ (sq) will be involved in the reaction. Places for these species are indicated by the blanks in the
