    In the example above, zinc metal is the reducing agent; it loses two electrons (is oxidized) and becomes Zn2+ ion. The reactant that gains electrons (is reduced) causes an oxidation and is called an oxidizing agent. Cu2+ ion gains two electrons (is reduced) to form copper metal. In order to have a complete, balanced redox.
