NEETChemistryElectrochemistry
Which oxidation reaction is preferred at the anode during the electrolysis of sodium chloride (NaCl) solution?
Options
- ANa+ (aq) → Na (s)
- BH 2 O (l ) → O 2 (g) + 4H+(aq) + 4e-
- CCl- (aq) → ½ Cl 2 (g) + e-
- DBoth B and C
Correct answer
D. Both B and C
Step-by-step solution
During the electrolysis of sodium chloride (NaCl) solution, at the anode the following oxidation reactions are possible:Cl- (aq) → ½ Cl 2 (g) + e-H 2 O (l ) → O 2 (g) + 4H+(aq) + 4e-
