Identify the correct representation of reaction occurring during chloralkali process

  1. 2NaCl(l) + 2H2O(l) → 2NaOH(l) + Cl2(g) + H2(g)
  2. 2NaCl(aq) + 2H2O(aq) → 2NaOH(aq) + Cl2(g) + H2(g)
  3. 2NaCl(aq) + 2H2O(l) → 2NaOH(aq) + Cl2(aq) + H2(aq)
  4. 2NaCl (aq) + 2H2O (l) → 2NaOH(aq) + Cl2(g) + H2(g)

Answer

Chloralkali process is an industrial process that is used to form sodium hydroxide by electrolysis of aqueous solution of sodium chloride. It forms sodium hydroxide with hydrogen and chlorine gas as by-products.

The correct option is D.
