Stokes radii of ions

If S[ is a weak base (low DN) and S2 is a strong base, cations are selectively solvated by S2 conversely, if Sj is a good acceptor (high AN) it will preferentially solvate the anion. As a consequence, the Stokes radii of ions generally change with the composition of a binary solvent. 

The main problem in the study of the role of these parameters on electrolyte conductivity is their interdependence. The change in composition of a binary solvent changes viscosity along with the dielectric permittivity, ion-ion association, and ion salvation, which may be preferential for one of the two solvents and therefore also changing the Stokes radii of ions.
