State Faraday's laws of electrolysis.
Answers
Faraday’s First Law
This law states that “the mass of a substance deposited or liberated at any electrode is directly proportional to the amount of charge passed” i.e., w a q (where w is the mass of the substance deposited or liberated and q is the amount of charge passed). This proportionality can be made into an equality by, w = zq
where z is the proportionality constant called the electrochemical equivalent. It is the mass of the substance in grams deposited or liberated by passing one coulomb of charge.
Faraday’s Second Law
This law states that “the mass of a substance deposited or liberated at any electrode on passing a certain amount of charge is directly proportional to its chemical equivalent weight”.
Answer:
Faradays first law: The mass of the substances (w) deposited or liberated at any electrode is directly proportional to the quantity of the charge (Q) passed through the electrolyte.
Mathematically, w ∝ Q or q ∝ I × t (Q = Current I × Time t)
Or w = Z × I × t
Where Z is called electrochemical equivalent.
Second law: When the same quantity of charge (Q) is passed through the solution of different electrolytes connected in series, the masses W1, W2, W3 of the substances deposited at the respective electrode are proportional to their equivalent masses E1, E2, and E3 respectively.
