Question 30.
Identify the correct representation of reaction occurring during chloralkali process.
(a) $2 NaCl(l) + 2 H_{2} O(l) \to 2 NaOH(l) + {Cl}_{2} (g) + H_{2} (g)$
(b) $2 NaCl(aq) + 2 H_{2} O(aq) \to 2 NaOH(aq) + {Cl}_{2} (g) + H_{2} (g)$
(c) $2 NaCl(aq) + 2 H_{2} O(l) \to 2 NaOH(aq) + {Cl}_{2} (aq) + H_{2} (aq)$
(d) $2 NaCl(aq) + 2 H_{2} O(l) \to 2 NaOH(aq) + {Cl}_{2} (g) + H_{2} (g)$

Solution

In chlor- alkali reaction, the state of ${Cl}_{2}$ and $H_{2}$ is gaseous, $H_{2} O$ is liquid and that of $NaCl$ and $NaOH$ is aqueous. Hence, the correct answer is option (d).
