Correct Answer: Electrolysis

Solution : The correct option is Electrolysis .

The two quantitative laws known as Faraday's laws of electrolysis are used to express the magnitudes of electrolytic effects. According to the laws (I), the amount of chemical change brought about by current at an electrode-electrolyte boundary is proportional to the amount of electricity used and (II) the amounts of chemical changes brought about by the same amount of electricity in various substances are proportional to their equivalent weights.
