Use the ion-electron method to balance each of the redox reactions:
After balancing the equations, answer the following questions for each reaction:
a) In the half reaction, which species is undergoing oxidation and which is undergoing reduction?
b)What are the possible oxidation states of chlorine in the reactions below?
1) Cl2(aq)->Cl^-(aq)+ClO3^-(aq) (basic conditions)
2)ClO^-(aq) + CrO2^-(aq)->Cl^-(aq)+CrO4^2-(aq)
