Explain the following:
(b) During the electrolysis of an aqueous solution of $N a C l, H^{+}$ ions are reduced at cathode and not $N a^{+}$ ions.

Solution

This reason for the situation is that $H^{+}$ ions lie below $N a^{+}$ ions in electrochemical series.
Electrochemical series is a list of elements in which elements are ordered in the increasing electrode potential values.
Because of this, the $H^{+}$ ions get discharged in preference to the $N a^{+}$ ions.
During electrolysis, a solution of $N a C l$ $H^{+}$ ions is reduced at the cathode as it lies below the $N a^{+}$ ions in an electrochemical series.
