Abstract

The derivation of ionic Stokes radii, r iSt, from ion mobilities (conductivities λ i ) and their relation to the actual ionic radii, of the bare or the hydrated ions, is followed through the years. It is concluded that such quantities as r iSt do not convey any useful information beyond what is already available in the λ i , and in particular that the r iSt should not be used for the estimation of solvation numbers. The concept of a Stokes radius of ions that are smaller than or commensurate with molecules of the solvent should be scrapped altogether.
