$Cl_{2(g)}$ gas is liberated at anode.

Vedclass · Answer

(D) $1$. In the electrolysis of molten $NaCl$,the reactions are: At cathode: $Na^+ + e^- \rightarrow Na_{(s)}$; At anode: $2Cl^- \rightarrow Cl_{2(g)} + 2e^-$.$2$. In the electrolysis of aqueous $NaCl$ (brine),the reactions are: At cathode: $2H_2O + 2e^- \rightarrow H_{2(g)} + 2OH^-_{(aq)}$; At anode: $2Cl^- \rightarrow Cl_{2(g)} + 2e^-$.$3$. Comparing both processes,$Cl_{2(g)}$ gas is liberated at the anode in both cases.
