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

Explanation:
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.
