Abstract
Solubility data are reported at 298.15K for LiF, NaF and, to a lesser extent, KF in aqueous mixtures of dimethylsulphoxide (DMSO), propanone, (acetone, AC) and 2-methylpropan-2-ol (tertiary butanol, t-BuOH) over virtually the entire solvent composition range. These data have been combined wherever possible with appropriate literature data to give standard Gibbs energies of transfer of the fluoride ion, Δt,G0(F−), from water to the aqueous-organic mixtures on the basis of the TATB assumption. Consistent with the poor acceptor properties of the cosolvents cf. H2O all three systems show highly positive values of Δt,G0(F−). However, both DMSO and t-BuOH systems show some interesting anomalies as a function of solvent composition.
