Electrode potential Electrode potential Electrode potential, "E", in chemistry or electrochemistry, according to a IUPAC definition, is the electromotive force of a cell built of two electrodes: The SHE is defined to have a potential of 0 V, so the signed cell potential from the above setup is SHE is cathode and electrode is anode Electrode potential appears at the interface between an electrode and electrolyte due to the transfer of charged species across the interface, specific adsorption of ions at the interface, and specific adsorption/orientation of polar molecules, including those of the solvent. Electrode potential is the electric potential on an
Fluoride selective electrode is given by the Nernst equation: where: Martin S. Frant and James W. Ross Jr. Electrode for Sensing Fluoride Ion Activity in Solution. Science 23 December 1966:Vol. 154. no. 3756, pp. 1553 - 1555 Fluoride selective electrode A fluoride selective electrode is a type of ion selective electrode sensitive to the concentration of the fluoride ion. A common example is the lanthanum fluoride electrode. In the lanthanum fluoride electrode, the sensing element is a crystal of lanthanum fluoride LaF, doped with europium fluoride EuF to create lattice vacancies. Such a crystal is an ionic conductor by virtue of the mobility
