Chapter 19, Problem 12E

Identify each of the following half-reaction as either an oxidation half-reaction or a reduction half-reaction: ${\text{Fe}}^{2+}\left(\text{aq}\right)\to {\text{Fe}}^{3+}\left(\text{aq}\right)+{\text{e}}^{-};{\text{Cl}}_2\left(\text{g}\right)+2{\text{e}}^{-}\to 2{\text{Cl}}^{-}\left(\text{aq}\right)$.

Write a balanced equation for the overall redox reaction.
