Q. What product are formed during the electrolysis of a concentrated aqueous solution of sodium chloride using an electrolytic cell in which electrodes are separated by a porous pot?
I. $NaOH(aq)$ II. $Cl_{2}(g)$
III. $NaClO_{3}(aq)$ IV. $H_{2}(g)$
V. $NaClO(aq)$
Select the correct choice.

Electrochemistry

Solution:

$NaCl (aq) \rightleftharpoons Na^{+}(aq) + Cl (aq)$
At anode $2Cl^{-} (aq) \to Cl_{2}(g) + 2e^{-}$
At cathode $2Na^{+} (aq)+ 2e^{-} \to 2Na(l)$
$2Na(l) + 2H_{2}O \to 2NaOH (aq) + H_{2}(g)$
$Cl_{2}(g)$ is formed at anode and $NaOH$ and $H_{2}$ are formed at cathode. Since cathode and anode are separated. Hence, there is no reaction between the products formed at the cathode and anode.
