Identify the correct representation of reaction occurring during chlor-alkali process.

Q. Identify the correct representation of reaction occurring during chlor-alkali process.

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

Answer: 2NaCl(aq) + 2H2O(l) →2NaOH(aq) + Cl2(g) + H2(g)
