According to a law postulated by ________, the amounts of different substances liberated by the same quantity of electricity passing through the electrolytic solution are proportional to their chemical equivalent weights.

Options

A. Joseph Fourier
B. John Dalton
C. Michael Faraday
D. Alfred Nobel

Answer

C

Explanation

According to a law postulated by Michael Faraday the amounts of different substances liberated by the same quantity of electricity passing through the electrolytic solution are proportional to their chemical equivalent weights. Faraday Law of Electrolysis states that the amount of chemical change produced by current at an electrode-electrolyte boundary is proportional to the quantity of electricity used, and the amounts of chemical changes produced by the same quantity of electricity in different substances are proportional to their equivalent weights.
