Solution

The correct option is D $2 N a C l (a q) + 2 H_{2} O (l) \to 2 N a O H (a q) + C l_{2} (g) + H_{2} (g)$
Chloro-alkali process is an industrial process for the electrolysis of sodium chloride. It is used to produce chlorine and sodium hydroxide. Aqueous sodium chloride or brine ina membrane cell.

At cathode: ${2 H}_{2} O + 2 e^{-} \to H_{2} + {2 O H}^{-}$

At anode: $2 {C l}^{-} \to {C l}_{2} + 2 e^{-}$

$2 N a C l (a q) + 2 H_{2} O \to {C l}_{2} (g) + H_{2} (g) + 2 N a O H (a q)$

Option $(D)$ suggests the correct reaction.
