The number of Faradays required to discharge one mole of ann ion at an electrode is equal to number of charges on the ion; The Equation involving Faraday’s Constant. SpletThe amount of electric charge carried by one mole of electrons (6.02 x 10 23 electrons) is called the faraday and is equal to 96,500 coulombs. The number of faradays required to produce one mole of substance at an electrode depends upon the way in which the substance is oxidized or reduced (see oxidation and reduction ). chris simmons lexington ky
