    Notizen: Abstract Starting from hierarchy of diffusion equations for the distribution functions in coordinate space, the general theory of conductance is developed and applied to Gurney-Friedman models for ion-ion interactions. The interaction potentials used consist of a hard core with Pauling radii and a Gurney cosphere with a steplike interaction law converging to the Coulomb law outside the Gurney sphere. For the simplest case of step potentials explicit formulas for the conductivity are given. For higher concentrations an integral equation corresponding to the mean-spherical approximation in equilibrium is proposed. The theory is compared with experimental data for 17 alkali halide electrolytes by fitting the Gurney parameters. It is shown that the variant of the theory which includes the feedback of the relaxation and electrophoretic forces describes also the data for associating 2-2 electrolytes.

    Thec logc contribution to the electrolyte conductance and Onsager's reciprocal relation (1979)
    Springer
    Journal of solution chemistry 8 (1979), S. 411-426 
    Details
    ISSN: 1572-8927
    Schlagwort(e): Electrolyte conductance ; Onsager's reciprocal relation ; c logc term ; continuity equation ; boundary conditions ; electrophoretic expansion ; unsymmetrical binary electrolytes

    Thema: Chemie und Pharmazie
    Notizen: Abstract The differential equations and the boundary conditions for the nonequilibrium binary distribution function of an unsymmetrical binary electrolyte are derived from the Ebeling-Falkenhagen continuity equation. The connection between the Onsager reciprocal relation and the binary distribution functions is shown. Further, Feistel's result for thec logc contribution to the conductance is extended to unsymmetrical binary electrolytes. The reason for the difference between Feistel's and Chen'sc logc term is explained, and the significance of Onsager's reciprocal relation for the calculation ofc logc and higher-concentration contributions of the conductance is discussed.
