Electrochemistry faraday's law
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 … See more Faraday's laws of electrolysis are quantitative relationships based on the electrochemical research published by Michael Faraday in 1833. See more Faraday discovered that when the same amount of electric current is passed through different electrolytes/elements connected in series, the mass of the substance liberated/deposited at the electrodes is directly proportional to their chemical equivalent/ See more • Electrolysis • Faraday's law of induction • Tafel equation See more A monovalent ion requires 1 electron for discharge, a divalent ion requires 2 electrons for discharge and so on.
