The aqueous solution of sodium chloride is known as brine solution. On electrolysis of brine solution, the following reactions are observed.

Oxidation reaction takes place at anode and reduction reaction takes place at cathode. The reaction

Anode: $2{\mathrm{OH}}^{-}\to \frac{1}{2}{\mathrm{O}}_2+{\mathrm{H}}_2\mathrm{O}+2{\mathrm{e}}^{⊝}$

Cathode: ${\mathrm{H}}_2\mathrm{O}+{\mathrm{e}}^{⊝}\to \frac{1}{2}{\mathrm{H}}_2+{\mathrm{OH}}^{⊝}$

Hydrogen and oxygen are electrode products. The remaining solution contain $\mathrm{NaOH}$.

Hence, $\mathrm{HCl}$ is not obtained
