Identify the correct representation of reaction occurring during chloralkali process.

Options

A. `2NaCl(l)+2H_(2)O(l)rarr2NaOH(l)+Cl_(2)(g)+H_(2)(g)`
B. `2 NaCl (aq)+2H_(2)O(aq)rarr2NaOH(aq)+Cl_(2)+H_(2)(aq)`
C. `2NaCl(aq)+2H_(2)O(l)rarr2NaOH(aq)+Cl_(2)(aq)+H_(2)(aq)`
D. `2NaCl(aq)+2H_(2)O(l)rarr2NaOH(aq)+Cl_(2)(g)+H_(2)(g)`

Answer

D

Explanation

`2NaCl(aq)+2H_(2)O(l)rarr2NaOH(aq)+Cl_(2)(g)+H_(2)(g)` (because state of `Cl_(2)` and `H_(2)` is gaseous, `H_(2)O` is liquid and that of `NaCl` and `NaOH` is aqueous).
