A. Z=At
B. w=ZAt
C. w=Z/At
D. Z= At/M
¨ The equation that represents the relationship of Faraday’s first law of electrolysis is B. w=ZAt.
¨ Where:
¨ w is the amount of substance produced or consumed during electrolysis
¨ Z is the electrochemical equivalent or amount of substance produced or consumed per unit charge
¨ A is the electric current
¨ t is the time.
Faraday’s first law of electrolysis states that the amount of chemical reaction taking place during electrolysis is proportional to the amount of electrical charge passed through the cell. Mathematically, it can be expressed as:
W = Q × Z
where W is the mass of substance deposited or liberated at the electrode, Q is the total electrical charge passed through the cell, and Z is the electrochemical equivalent of the substance.
Faraday’s second law of electrolysis states that when the same amount of electrical charge is passed through different electrolytes, the amount of substance liberated or deposited at the electrodes is directly proportional to the equivalent weight of the substance. Mathematically, it can be expressed as:
W1/W2 = E1/E2
where W1 and W2 are the amounts of different substances liberated or deposited at the electrodes, E1 and E2 are the equivalent weights of the substances.
