VLE predictions revisited
This work deals with the use of experimental solubility data in predicting phase equilibria data. The complications caused by use of solubility data for thermodynamical or data specialists is considered. Equilibrium K constants can be calculated from solubility data without knowing the vapor pressure of the solvent when Henry's law region exists. Solubility coefficients of different bases are shown to be identical. Techniques in applying the equation of state instead of obtaining fugacity coefficients are shown. Improvement in data when the assumption of Henry's law is eliminated is given. Simplifications within Henry's law region are studied. The confusion between the two definitions of the Bunsen coefficient alpha is discussed. The equivalency of these two expressions is not believed to have ever been shown in the literature.
