Faraday's first law of electrolysis
Mass of substance deposited or liberated at any electrode is directly proportional to the quantity of electricity passed through the electrolyte.
m = z I t
z = electrochemical equivalent = atomic mass / nF
F = Faraday constant = 96500 C moL-1
I = Current in Ampere
t = time in seconds
Electrochemical equivalent
if I = I A, T = I s
m = z
It is the mass of substance deposited when a current of 1A is passed for 1 second.
Faraday's second law of electrolysis
When the same quantity of electricity is passed through solutions of different electrolytes connected is series, masses of substances produced at electrodes is directly proportional to their equivalent masses.
\(\frac{m_1}{m_2}=\frac{E_1}{E_2}\)
