Electrochemistry emf
WebIn 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". Webis the value of the standard emf of a cell in which molecular hydrogen is oxidized to solvated protons at the left-hand electrode. For example, the standard potential of the Zn2+ Zn electrode, denoted E°(Zn2+ Zn), is the emf of the cell in which the reaction Zn2+(aq) + H 2 → 2H +(aq) + Zn takes place under standard conditions.

WebMar 10, 2024 · The EMF of the cell is the potential of the cathode subtract that of the anode, consistent with ##\Delta G = -nF\varepsilon##. If the cell is running as a galvanic cell/discharging, the EMF should be positive. If it is charging, the cathode (the one gaining electrons) is now negative and at lower potential, so the EMF should be negative.
