State Faraday's laws of electrolysis and mention their uses.

(N/A) Michael Faraday was the first scientist who described the quantitative aspects of electrolysis. After his extensive investigations on the electrolysis of solutions and melts of electrolytes,Faraday published his results during $1833-34$ in the form of the following two laws of electrolysis:
$(i)$ First Law: The amount of chemical reaction which occurs at any electrode during electrolysis by a current is proportional to the quantity of electricity passed through the electrolyte (solution or melt).
$(ii)$ 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).
Uses: These laws are used to calculate the amount of substance deposited or liberated at electrodes,to determine the equivalent mass of metals,and in industrial processes like electroplating and electrorefining.
