Answer:
First law: The mass of a substance liberated at the electrode is directly proportional to the quantity of electricity passed through the electrolyte.
m ∝ Q or m = Z.Q
Q = I x t
m = Z x I x t where Z = electrochemical equivalent.
Second law: When same quantity of electricity is passed through different electrolytes connected in series then the masses of substance liberated at the electrodes are in the ratio of their chemical equivalent masses.
