| Resumen en inglés | A method to correlate and predict salt solubilities in mixed solvents using a UNIQUAC+Debye-Hückel model is developed. The UNIQUAC equation is applied in a form with temperature-dependent parameters. The Debye-Hückel model is extended to mixed solvents by properly evaluating the dielectric constants and the liquid densities of the solvent media. To normalize the activity coefficients, the symmetric convention is adopted. Thermochemical properties of the salt are used to estimate the solubility product. It is shown that the proposed procedure can describe with good accuracy a series of salt solubility measurements in aqueous organic solvent mixtures |
