New perspectives in the transport of electrolyte solutions
Résumé
We recently obtained simple expressions for the variation with concentra- tion of the transport coeficients of electrolytes in aqueous solution, namely: self- diffusion, conductance of two simple ionic species, conductance of three simple ionic species and micellar systems. The FuossOnsager continuity equations were solved using modern equilibrium pair distribution functions such as the MSA (mean spher- ical approximation) leading to explicit expressions for the variation of the transport coefficients with concentration. These expressions are in good agreement with the experimental values for both unassociated and associated electrolytes and micellar solutions.
