Which from following is NOT true about electrolysis of molten NaCl ?

Options

  1. ACl ₂ gas is liberated at anode.
  2. BNa is deposited at cathode.
  3. CThe decomposition of NaCl into Na _ ( s ) and Cl _ 2( ~g ) is spontaneous.
  4. DElectrical energy is used to carry out the reaction.

Correct answer

C. The decomposition of NaCl into Na _ ( s ) and Cl _ 2( ~g ) is spontaneous.

Step-by-step solution

The decomposition of NaCl into Na _ ( s ) and Cl _ 2( ~g ) is not spontaneous as cell potential for the process is negative.
