In electrolysis:

A
Positive ions move toward the positive electrode and negative ions toward the negative electrode.
✓
Positive ions move toward the negative electrode and negative ions toward the positive electrode.
C
Both ions move toward both the electrodes in equal amounts until they are balanced.
D
None of the above.

✓

Answer

Correct option: B.

Positive ions move toward the negative electrode and negative ions toward the positive electrode.

The process in which electrical current is passed through a substance to effect a chemical change. The chemical change is one in which the substance loses or gains an electron $($oxidation or reduction$)$ is called electrolysis.
The process is carried out in an electrolytic cell, an apparatus consisting of positive and negative electrodes held apart and dipped into a solution containing positively and negatively charged ions. In this process, positive ions move toward the negative electrode and negative ions toward the positive electrode.
