Identify the correct representation of reaction occurring during chloralkali process

(A) 2NaCl(l) + 2H 2 O(l) → 2NaOH(l) + Cl 2 (g) + H 2 (g)

(B) 2NaCl(aq) + 2H 2 O(aq) → 2NaOH(aq) + Cl 2 (g) + H 2 (g)

(C) 2NaCl(aq) + 2H 2 O(l) → 2NaOH(aq) + Cl 2 (aq) + H 2 (aq)

(D) 2NaCl (aq) + 2H 2 O (l) → 2NaOH (aq) + Cl 2 (g) + H 2 (g)

 

Answer

Chlor-Alkali process is a method for the industrial production of sodium hydroxide and chlorine by the electrolysis of sodium chloride solution.

 

Since the electrolysis is carried out in aqueous medium, NaCl is taken in aqueous medium. Cl 2 and H 2 gas are evolved and the NaOH produced during the reaction is also in aqueous medium.

 

Hence, the correct representation of the reaction is:
