Which one of the following statements is correct for electrolysis of brine solution?

Question

Canvas Classes · Accepted Answer

Strategy:
 Identify the reduction half-reaction at the cathode during the electrolysis of aqueous  (brine). Water is more easily reduced than .

Step 1: Analyze cathode reaction
Water undergoes reduction because its reduction potential is higher than that of sodium ions:

This results in the formation of Hydrogen gas and Hydroxide ions at the electrode surface.

Step 2: Verify options
-  is formed at the anode.
-  is formed at the cathode.
-  ions are explicitly formed in the cathode compartment
