Abstract
:
Application of the empirically modified form of Stokes’ law proposed by Gill (1977-1979) to calculate ionic radii in non- aqueous solvents was carried out, using s-alkylisothiouronium bromide, iodide and picrate salts. The required single ionic conductance was obtained from literature. The comparison between the summation of the hydrodynamic radii (ri+ + ri-) and the distance (R) obtained from Fuoss’ conductance equation (1975—1980) indicates success of Gill’s equation in giving good information about the behavior of an ion in solution. In all cases under investigation, (ri) was found to represent the solvated ionic radius; hence the solvent ــ separated ion-pair model is preferred.
