Question Explanation:

Matching electrolysis products at electrodes.

Concept:

This question is based on electrolysis.

Solution:

(A) Aqueous HCl solution: $H_{2}$ is evolved at the cathode and $O_{2}$ at the anode.

So, A matches with (p) and (q).

(B) Aqueous NaCl solution: $H_{2}$ is evolved at the cathode and $Cl_{2}$ at the anode.

So, B matches with (q) and (r).

(C) Molten $NaCl : Na$ is deposited at the cathode and $Cl_{2}$ is evolved at the anode.

So, C matches with (r) and (s).

(D) Aqueous $AgNO_{3}$ solution: Ag is deposited at the cathode and $O_{2}$ is evolved at the anode.

So, D matches with (p) and (t).

List - I	List - II
(A) Aqueous solution of HCl	(p) $O_{2}$ evolved at anode
(B) Aqueous solution of NaCl	(q) $H_{2}$ evolved at cathode
(C) Molten NaCl	(r) $Cl_{2}$ evolved at anode
(D) Aqueous solution of $AgNO_{3}$	(s) Na deposited at cathode
	(t) Ag deposited at cathode
