WebAug 15, 2024 · Faraday's Law. In every electrochemical process, whether spontaneous or not, a certain amount of electric charge is transferred during the oxidation and reduction. …
Michael Faraday reported that the mass (m) of elements deposited at an electrode is directly proportional to the charge (Q; SI units are ampere seconds or coulombs). Here, the constant of proportionality, Z, is called the electro-chemical equivalent (ECE) of the substance. Thus, the ECE can be defined as the mass of the substance deposited/liberated per unit charge.
