Select the correct answer from the list given in brackets :
When dilute sodium chloride is electrolysed using graphite electrodes, the cation is discharged at the cathode most readily. `[Na^(+) , OH^(-) , H^(+) , Cl^(-)]`.

A

`Na^(+)`

B

`OH^(-)`

C

`H^(+)`

D

`Cl^(-)`

Text Solution

Verified by Experts

The correct Answer is:
C
Hydrogen ions are discharged at the cathode. As it is a dilute NaCl solution, therefore, the concentration of `H^(+)` ions is more.
