| 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. \[C{{l}_{2}}(g)\] |
| III. \[NaCl{{O}_{3}}(aq)\] |
| IV. \[{{H}_{2}}(g)\] |
| V. \[NaClO(aq)\] |
| Select the correct choice. |
A) I, II and V
B) I, II and IV
C) I and II
D) I, III and V
Correct Answer: B
Solution :
[b] \[NaCl(aq)\rightleftharpoons N{{a}^{+}}(aq)+Cl(aq)\] At anode \[2C{{l}^{-}}(aq)\to C{{l}_{2}}(g)+2{{e}^{-}}\] At cathode \[2N{{a}^{+}}(aq)+2{{e}^{-}}\to 2Na(l)\] \[2Na(l)+2{{H}_{2}}O\to 2NaOH(aq)+{{H}_{2}}(g)\] \[C{{l}_{2}}(g)\]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 product formed at the cathode and anode.
