Conductance equation of dilute mixed strong electrolytes. II. Hydrodynamic and osmotic terms in relaxation field

The hydrodynamic and osmotic terms in the relaxation field are computed up to order linear in concentration for a dilute solution of mixed strong electrolytes using the primitive model. The computation is based on the relative function μ_ji computed in part earlier for the purely electrostatic interaction and in part in this work for the hydrodynamic interaction assuming the adequacy of the Fuoss velocity field. The results are compared with the earlier computations of Fuoss and Onsager, Murphy and Cohen, and Falkenhagen, Ebeling, and Kraeft. It is found that some terms of the new results are in agreement with the earlier computations and the other terms represent an improved computation.
