Solubilities of salts and kinetics of reactions involving inorganic complex ions in aqueous acetone mixtures. Derivation of transfer chemical potentials for ions in these aqueous mixtures at ambient pressure and 298.2 K

Abstract

Solubilities of salts, including those formed by complex ions, are reported for aqueous solutions and for solutions in aqueous acetone mixtures. Data from many sources are combined to yield transfer chemical potentials for an extensive range of ions (at 298 K and ambient pressure) based on the TATB assumption, which assumes that transfer chemical potentials for Ph₄As⁺ and Ph₄B^– ions are equal. Derived transfer parameters are used in analyses of kinetic data describing substitution, isomerisation and redox reactions. Transfer parameters point towards the importance of ion size, electric charge and hydrophilic/hydrophobic character in determining solvation of ions in binary aqueous mixtures.
