Express Faraday Law Of Electrolysis ?
Quantitative measurements made by Faraday (1833) contributed to the understanding of the process occurring in electrolytic cells and showed a stinking relation between the electrolytic behavior and the chemical properties of various substance. Faraday established by experiment the following two laws of electrolysis: First law: The mass of substance separated in electrolysis is proportional to the quantity of in electrolysis is proportional to the quantity of electricity that passes. Second law: The mass of substance deposited is electrolysis is proportional to the quantity of electricity that passes. Faraday’s law may be expressed by the following symbolic statements: m ∝ Q (Q = It) m ∝ c (c = (atomic mass)/(valence )) When m = kcQ = zQ = zIt (z = kc) Where k is a proportionality constant, whose value depends only upon the units involved, mis the mass deposited, and z is a constant for a given substance (but different for different substance), which is known as the electrochemical equivalent of the substance under consideration. The electrochemical equivalent of a substance is the mass deposited per unit charge. In the mks system it numerically the number of kilograms deposited in one second by an unvarying current of one ampere.
