Solution

In the electrolytic cell, during reaction redox reaction takes place.
Redox reaction is a combination of oxidation and reduction reactions that are taking place simultaneously.
In the reduction reaction, there is the gain of electrons due to which the metal or the rod possesses a negative charge on it.
Hence, the ions which discharge on the negative electrode during electrolysis gain electrons. Thus the ions are said to be reduced.
