Utilize the ion-electron method to balance each of the redox reactions
After balancing the equations answer the subsequent questions for each reaction:
a) In the half reaction which species is undergoing oxidation and which is undergoing reduction?
b) Explain 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) (basic conditions)
