Abstract: Our 5-year study on the "abnormally high" electrical conduction in pure liquid water led us to the formulation of the successful Born-Von Karman lattice model of liquid water for protonic transport. Consistent with the Bernal-Fowler ice rule which was proven by Pauling’s Residual Entropy. Theory and Giauque's specified heat measurements, our hexagonal close packed lattice of Oxygen with tetrahedral point symmetry, extends through a considerable range of bulk liquid water, accounting for the “Soft” mechanical properties of the confined fluidic water. Each primitive unit cell of the Oxygen Lattice contains four water molecules, which is the basis of the many-body oxygenic or wateric photons and protonic phonons. The electrical charge carrier concentration and mobility of the point-mass protons in pure water can be represented by two self-consistent models: (1) the bipolar protonic energy band model of protons and prohols (proton-holes), in protonic materials, analogous to the bipolar electronic energy band model of electrons and holes in electronic solids and materials, (2 ) the unipolar (proholess) protonic energy band model with half (8) as many protons as (16) proton traps of three-charge-states. Bipolar and Unipolar protonic transports (drift-diffusion-trapping) are rate limited by mobile protons detrapping at the (16) dynamic proton-trapping centers, involving the absorption of only one protonic phonon in each detrapping transition, while its inverse, the trapping of the mobile proton with emission of also one protonic phonon, has a much higher rate. Between the trapping and detrapping transitions, the mobile protons are scattered by wateric phonons with a distribution of energies (Debye Mode). The international standard experimental generation-recombination-trapping data of the 50-year-old “ion” product (or PH) at thermodynamic equilibrium and the 40-year-old mobilities of the two “ions” at small deviation from thermodynamic equilibrium, and the reported experimental phonon energies, are used by us to extract the ion and proton concentrations and proton mobilities, anticipated by our water physics and its model. Some important potential applications of our water physics and model are described.
