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,
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
