On Electrochemical Managing the Properties of Aqueous Coolant

Abstract

Liquid water as a chemical compound with the wide band gap is characterized by varying their Fermi level as a linear identifier of water oxidation-reduction potential (ORP). This potential is the management tool for changing chemical properties of the aqueous coolant by forced shifting Fermi level in the band gap at the expense of insignificant deviation (|z| 0) with the negative ORP is realized when Fermi level is shifted to the local donor level, eHO, by electro-reducing the aqueous coolant in the electrochemical cell with the strongly polarized anode and the quasi-equilibrium cathode, occupying eH2O by electrons, and forming hydroxonium radicals, H3O, as the strongest reducers. Opposite, the hyperstoichiometric state (z<0) with the positive ORP is realized in the electrochemical cell with the strongly polarized cathode and the quasi-equilibrium anode when Fermi level is shifted to the local acceptor level, radicals, eOH, as the strongest oxidizers. eOH, forming in water hydroxyl.
