What products are formed during, the electrolysis of a concentrated aqueous solution of $NaCl$ ?

$(I)\,Cl_2(g)$ $(II)\,NaOH(aq)$ $(III)\,H_2(g)$

$I$ only

$I$ and $II$ only

$I$ and $III$ only

$I,\,II$ and $III$

Solution

The electrolysis of a concentrated solution of $\mathrm{NaCl}$ gives $(\mathrm{I}) \mathrm{Cl}_{2},(\mathrm{II}) \mathrm{NaOH}(\mathrm{aq})$ and $(\mathrm{III}) \mathrm{H}_{2}(\mathrm{g})$

$2 \mathrm{NaCl}(\mathrm{aq})+2 \mathrm{H}_{2} \mathrm{O} \rightarrow 2 \mathrm{NaOH}(\mathrm{aq})+\mathrm{H}_{2}(\mathrm{g})+\mathrm{Cl}_{2}(\mathrm{g})$

Hence, the correct option is $\mathrm{D}$
