Laws: Faraday's Laws of Electrolysis
Faraday's laws of electrolysis are quantitative laws that describe the effects of electrolysis. They are:
First Law: The mass of any substance deposited or liberated at any electrode is directly proportional to the quantity of electricity passed through the electrolyte.
W ∝ Q
W = ZQ (Z = electrochemical equivalent)
W = ZIt
\[(Z=\frac{\text{Equivalent Weight}}{96500})\]
Second Law: When the same quantity of electricity is passed through solutions of different electrolytes connected in series, the weight of substances produced at the electrodes is directly proportional to their equivalent weights.
\[\frac{\text{Weight of }M_1\mathrm{~Deposited}}{\text{Weight of }M_2\mathrm{~Deposited}}=\frac{\text{Eq. wt. of }M_1}{\text{Eq. wt. of }M_2}\cdots\cdots\]
