Here p denotes the chemical potential, z the signed valencies of the ions, F the Faraday number and 9 the electrical potential. The flow of solvent is zero in the SF frame. The electrical current density has to vanish, i.e.,... 

Two atoms exchanging electrons in a solution are a separate galvanic microelement. The atoms serve as electrodes and water serves a conductor. In the absence of equihbrium between these electrodes arises potential difference AE, which forces electrons to pass from one atom to the other, thereby generating electric current. The value of the maximum useful work of such current is proportionate to the charge carried by it. This charge is equal to the number of electrons, i.e., to the stoichiometric coefficient of the electron in semi-reactions multiplied by the Faraday number... 

In this section, the governing equations of the electrokinetics in the nanochaimels will be briefly reviewed. In these equations, (p is the electric potential, E is the electric field, c, is the concentration of ion species, and also p and u are the pressure and the velocity vector, respectively. The constants include permittivity (ao r), medium density (p), the Faraday number (F), fluid viscosity (rj), valance number (z,), diffusion coefficient (D,), and mobility (p,) of ion species type i.

In Eqs. (122) and (123), M(Hg) is an alkali metal amalgam electrode, MX the solvated halide of the alkali metal M at concentration c in a solvent S, and AgX(s)/Ag(s) a silver halide-silver electrode. Equation (124) is the general expression for the electromotive force " of a galvanic cell without liquid junction in which an arbitrary cell reaction 0)1 Yi + 0)2Y2 + coiYi + , takes place between k components in v phases. In Eq. (124) n is the number of moles of electrons transported during this process from the anode to the cathode through the outer circuit, F the Faraday number, and the chemical potential of component Yi in phase p. Cells with liquid junctions require the electromotive force E in Eq. (124) to be replaced by the quantity E — Ej), where Ey> is the diffusion potential due to the liquid junction. The standard potential E° for the cell investigated by Eq. (122) is given by the relationship...
