Question

Correct statement about electrolysis of aqueous NaCl is:

पर्याय

• H₂ gas liberated at cathode.

• Cl₂ gas liberated at cathode.

• H₂ gas liberated at anode.

• O₂ gas liberated at anode.

Answer 1

H₂ gas liberated at cathode.

Explanation:

In electrolysis of aqueous NaCl (brine), at the cathode (reduction), water is reduced to liberate H₂ gas. At the anode, Cl⁻ is oxidised to Cl₂ gas. H₂ is liberated at the cathode, not at the anode.
