Relaxation Term of the Limiting Law of the Conductance of Electrolyte Mixtures

Abstract

The calculation of the limiting-law terms from the cluster theory of conductance, as presented in recent papers, is extended to solutions of mixtures of electrolytes. The more general evaluation of one of the cluster integrals required for this purpose is achieved by using some results from the theory of symmetric polynomials. The resulting relaxation term is very different in form from that of Onsager and Kim but, at least for solutions of three solute species, the two theories give the same numerical results for the ionic conductances in a variety of systems.
