Attempted the problem, would like to know how to solve step by step.

Cl2(g) -> Cl- (aq) + ClO- (aq)

Solution

Cl2 (g) + 2H2O (aq) ---> 2ClO- (aq) + 2e + 4H+ (aq)--- (1) oxidation Cl2 (g) + 2e ---> 2Cl- (aq)--- (2) reduction Add the two (1) + (2) to get the overall reaction 2Cl2 (g) + 2H2O (aq) ---> 2Cl- (aq) + 2ClO- (aq) + 2H+ (aq)
