Question

Find out products of hydrolysis of NaCl solution at cathode and anode. (A) H 2, Cl 2 (B) Cl 2, H 2 (C) Na , Cl 2 (D) Na , O 2

At cathode, reduction reaction with higher value of E0 is preferred while at anode oxidation reaction with lower value of E0 is preferred. Cathode: 2 H 2 O 2 e H 2+2 OH Anode: 2 Cl Cl 2+2 e

Q. Find out products of hydrolysis of $N a Cl$ solution at cathode and anode.

$H_{2}, C l_{2}$

$C l_{2}, H_{2}$

$N a, C l_{2}$

$N a, O_{2}$

At cathode, reduction reaction with higher value of $E^{0}$ is preferred while at anode oxidation reaction with lower value of $E^{0}$ is preferred.
Cathode: $2 H_{2} O 2 e H_{2} + 2 O H$
Anode : $2 Cl C l_{2} + 2 e$
