Abstract
The stability constants of 1: 1 sulfate complexes (ion pairs) at 298 K are approximately calculated for all tervalent actinides and lanthanides, scandium, yttrium, and for alkali, earth-alkali, and some bivalent transition metals in aqueous solutions. The method used consists in integrating the function of the ligand distribution density with respect to a cation and allows either only solvent-separated ion pairs or all types of ion pairs to be taken into account in the calculation of constants. The dominance of solvent-separated ion pairs in infinitely dilute solutions is shown for lanthanides, actinides, and for the majority of the considered metals by comparison with experimental data.
