Approximate individual ion values of β (or B) in extended Debye-Hückel theory for uni-univalent aqueous solutions at 298.15 K

Individual values for β (or B) in extended Debye-Hückel theory have been estimated assuming additivity of individual ion values. Although known not to be rigorous, the results appear sufficiently accurate to be useful and to warrant further investigation. The individual β values can be partially correlated with the standard entropies of the aqueous ions.
