Fawcett Acidity and Basicity

Home   ::   Tables for Chemistry   ::   Eluotrope series
The acidity (Ap) and basicity (Bp) values of Fawcett are obtained from the solvation energy of monoatomic ions interpreted using the mean spherical approximation.

See L. Blum, W. R. Fawcett; "Application of the mean spherical approximation to describe the Gibbs solvation energies of monovalent monoatomic ions in polar solvents", J. Phys. Chem. 96 (1992) 408–414, and W. R. Fawcett; "Acidity and basicity scales for polar solvents", J. Phys. Chem. 97 (1993) 9540–9546.
