Balancing oxidation-reduction equation

Question

Balance the following oxidation-reduction reactions that occur in basic solution using the half-life reaction method.

Cl2 (g) →Cl− (aq) +OCl− (aq)

Answer 1

Cl₂ + 2e- ==> 2Cl^- reduction

Cl₂ + 2H₂O ==> 2OCl^- + 4H⁺ + 2e- oxidation

______________________________________

2Cl₂ + 2H₂O ==> 2Cl^- + 2OCl^- + 4H⁺ ... balanced for mass and charge
