Identify the correct represention of reaction occureing during chloralkali process.

Options

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

Answer

D

Explanation

When electricity is passed through an aqueous solution of sodium chloride (called brine), it decomposes to form sodium hydroxide. The process is called the chloralkaline process because of the products formed-chlor for chlorine and alkali for sodium hydroxide.
