Explain how electrolysis is an example of redox reaction.

Solution

The reaction at the cathode involves the reduction of cations as gain electrons to become neutral atoms while that at anode involves oxidation of anions as they lose electrons to become neutral.

Example: Dissociation of sodium chloride during electrolysis.
$$NaCl\rightleftharpoons Na^+ +Cl^-$$
At cathode: $$Na^+ +e^- \to Na$$ (Reduction)
At anode: $$Cl^- -e^- \to Cl$$ (oxidation)
$$Cl+Cl\to Cl_2$$
Overall reaction: $$2NaCl\to 2Na+Cl_2$$
