Faraday's Second Law of Electrolysis states that the amount of substance that undergoes electrolysis is directly proportional to the quantity of electric charge passed through the electrolyte. In simpler terms, if you pass more electric current through an electrolyte, more of the substance will be deposited or dissolved at the electrodes. This law helps us understand the relationship between electricity and chemical reactions in electrolysis, allowing us to calculate the amount of material produced based on the charge used.
