Balance the following oxidation–reduction equation. The reactions occur in a basic aqueous solution.
Cd2++ H 2S → Cd + S 8
S2- + F2 → SO42- + F-
Cr + NO3- → Cr(OH)4- + NH3
MnO4- + C2O42- → MnO2 + CO2
Solution :-
The redox reactions are balanced in the basic solution by adding the OH- ions at the final steps of the balancing.
Following image shows the balancing steps and final balanced equation for the each reaction
