Electrochemistry reduction potential
WebElectrochemical cells • Electrochemical Cells involve separate redox reactions, ne-transfer from reactants to electrodes (or visa-versa) via an electrical conductor • Components of electrochemical cells: • an anode, the electrode at which oxidation occurs, • a cathode , the electrode at which reduction occurs, WebView history. In electrochemistry, standard electrode potential , or , is a measure of the reducing power of any element or compound. The IUPAC "Gold Book" defines it as: "the value of the standard emf ( electromotive force) of a cell in which molecular hydrogen under standard pressure is oxidized to solvated protons at the left-hand electrode".
