IX-II. Balance each of the following redox reactions.
If you need some help, review the steps involved in balancing redox reactions.
| (a) | Cr2O72- (aq) + I- (aq) --> Cr3+ (aq) + IO3- (aq) |
|---|---|
| in acidic solution | |
| (b) | MnO4- (aq) + CH3OH (aq) --> Mn2+ (aq) + HCO2H (aq) |
| in acidic solution | |
| (c) | As (s) + ClO3- (aq) --> H3AsO3 (aq) + HClO (aq) |
| in acidic solution | |
| (d) | Pb(OH)42- (aq) + ClO- (aq) --> PbO2 (s) + Cl- (aq) |
| in basic solution | |
| (e) | H2O2 (aq) + ClO2 (aq) --> ClO2- (aq) + O2 (g) |
| in basic solution | |
| (f) | MnO4- (aq) + Cl- (aq) --> Mn2+ (aq) + Cl2 (aq) |
| in acidic solution | |
