What will happen if an aqueous solution of NaCl is subjected to electrolysis?

Options

  1. ASodium metal will be deposited at the cathode and chlorine gas will be evolved at the anode.
  2. BHydrogen gas will be evolved at the cathode and oxygen gas will be evolved at the anode.
  3. CSodium ions will migrate towards the anode, while chloride ions will migrate towards the cathode.
  4. DSodium ions will migrate towards the cathode, while chloride ions will migrate towards the anode.

Correct answer

B. Hydrogen gas will be evolved at the cathode and oxygen gas will be evolved at the anode.

Step-by-step solution
