The factors affecting the quantities of matter liberated during the process of electrolysis were investigated by Faraday.
First Law : The mass of a substance liberated at an electrode is directly proportional to the charge passing through the electrolyte. If an electric current I is passed through an electrolyte for a time t, the amount of charge (q) passed is I t. According to the law, mass of substance liberated (m) is m α q or m = zIt where Z is a constant for the substance being liberated called as electrochemical equivalent. Its unit is kg C–1. The electrochemical equivalent of a substance is defined as the mass of substance liberated in electrolysis when one coulomb charge is passed through the electrolyte.
Second Law : The mass of a substance liberated at an electrode by a given amount of charge is proportional to the chemical equivalent of the substance. If E is the chemical equivalent of a substance, from the second law m α E
