Answer #1

half reactions are:
ClO2 + 5e- ----> Cl-
ClO2 --->ClO3- + 1 e-

adding afcter balancing number of electron

6ClO2 (aq) ----> 5ClO3- (aq) + Cl- (aq)

Balance Oxygen:

6ClO2 (aq) +3H2O (l) ----> 5ClO3- (aq) + Cl- (aq)

Balance H

6ClO2 (aq) +3H2O (l) ----> 5ClO3- (aq) + Cl- (aq) + 6H+(aq)

multiply both sides by 6 OH-

6ClO2 (aq) +3H2O (l) + 6OH-(aq) ----> 5ClO3- (aq) + Cl- (aq) + 6H+(aq) + 6OH-(aq)

6ClO2 (aq) +3H2O (l) +  6OH-(aq) ----> 5ClO3- (aq) + Cl- (aq) + 6H2O (l)

6ClO2 (aq) +  6OH-(aq) ----> 5ClO3- (aq) + Cl- (aq) + 3H2O (l)
