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.
