Faraday’s Laws of Electrolysis are widely applicable in the process of electrolysis due to the extensive investigations on electrolysis of solutions and melts of electrolytes, Faraday gave his results during in the form of the following well known Faraday’s two laws of electrolysis:

(i)                  First Law: The amount of chemical reaction which occurs at any electrode during electrolysis by a current is directly proportional to the quantity of electricity passed through the electrolyte.

(ii)                 (ii) Second Law: The amounts of different substances liberated by the same quantity of electricity passing through the electrolytic solution are proportional to their chemical equivalent weights (Atomic Mass of Metal ÷ Number of electrons required to reduce the cation).

The weight of silver (at. wt. = 108 ) displaced by a quantity of electricity which displaces 5600 mL of $O_2$ at STP will be
