उत्तर
Correct statement about electrolysis of aqueous NaCl is 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.
