Assertion : Electrolysis of NaCl_ (a q) produces Na metal. Reason :...

Assertion : Electrolysis of NaCl(aq)\mathrm{NaCl}_{(a q)} produces Na\mathrm{Na} metal. Reason : Na+\mathrm{Na}^{+}is obtained at cathode.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

Electrolysis of brine solution (NaCl(aq))\left(\mathrm{NaCl}_{(a q)}\right) produces NaOH,H2\mathrm{NaOH}, \mathrm{H}_2 and Cl2\mathrm{Cl}_2. Hydrogen gas is obtained at cathode.
