(a) Faradaya's first law of electrolysis: The amount of substance deposited during electrolysis is directly proportional to quantity of electricity passed. Faradaya's second law of electrolysis: If same charge is passed through different electrolytes, the mass of substance deposited will be proportional to their equivalent weights. (b) Faradaya's first law of electrolysis: The amount of substance deposited during electrolysis is directly proportional to quantity of electricity passed. Faradaya's second law of electrolysis: If same charge is passed through different electrolytes, the mass of substance deposited will be inversely proportional to their equivalent weights. (c) Faradaya's first law of electrolysis: The amount of substance deposited during electrolysis is indirectly proportional to quantity of electricity passed. Faradaya's second law of electrolysis: If same charge is passed through different electrolytes, the mass of substance deposited will be proportional to their equivalent weights.(d) Faradaya's first law of electrolysis: The mass of substance deposited during electrolysis is directly proportional to quantity of electricity passed. Faradaya's second law of electrolysis: If same charge is passed through different electrolytes, the volume of substance deposited will be proportional to their equivalent weights.
