ox·i·da·tion-re·duc·tion po·ten·tial (E0+),

the potential in volts of an inert metallic electrode measured in a system of an arbitrarily chosen ratio of [oxidant] to [reductant] and referred to the normal hydrogen electrode at absolute temperature; it is calculated from the following equation; where R is the gas constant expressed in electrical units, T the absolute temperature (Kelvin), n the number of electrons transferred, F the faraday, and E0 the normal symbol for the potential of the system at pH 0; for biologic systems, E0' is often used (in which pH = 7). Compare: Nernst equation.
Synonym(s): redox potential

oxidation-reduction potential

measure of the capacity of an element or compound, usually contained in half-cells consisting of electron donor and its conjugate electron acceptor, to donate electrons in aqueous medium. Often called redox potential and given the symbol EO or E′O for pH 7.0. Electrons flow from the half-cell of lower to that of higher redox potential.
