The symbol for the oxidation-reduction (redox) potential. The redox potential is the electric potential energy needed to transfer a mole of electrons from an oxidant to a reductant. The use of catalysts to remove contaminants from water supplies during water treatment relies on measurements of the redox potential. It is usually referenced to the potential of a standard electrolytic cell.
n the symbol for oxidation-reduction potential, which is regarded as a significant factor in the protection of the body against anaerobic bacteria. The eH of living tissue of pH level 7.4 is about 0.12 volt.
