Electrode potential Potential of a cell assembled of two electrodes can be determined from the two individual electrode potentials using or, equivalently, This follows from the IUPAC definition of the electric potential difference of a galvanic cell, according to which the electric potential difference of a cell is the difference of the potentials of the electrodes on the right and the left of the galvanic cell. When Δ"V" is positive, then positive electrical charge flows through the cell from the left electrode (anode) to the right electrode (cathode). Electrode potential Electrode potential, "E", in chemistry or electrochemistry, according to a IUPAC definition,
Standard hydrogen electrode Standard hydrogen electrode The Standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials. Its absolute electrode potential is estimated to be at 25 °C, but to form a basis for comparison with all other electrode reactions, hydrogen's standard electrode potential ("E") is declared to be zero volts only at 298K. Potentials of any other electrodes are compared with that of the standard hydrogen electrode at the same temperature. Hydrogen electrode is based on the redox half cell: This redox reaction occurs at a platinized platinum electrode. The electrode is
