Estimation from Henrys Law Constant

Estimation from Henry s Law Constant In certain cases the water solubility at temperature T can be calculated as the ratio of the liquid vapor pressure at saturation, PSL, and Hc, or as the ratio of the solid vapor pressure at saturation, P, and Hc, if these data are known at T  

This approach has been applied for hydrocarbons, halogenated hydrocarbons, and various classes of pesticides. However, if the solute and water are mutually soluble into each other in appreciable amounts (e.g., 5% mol), these equations are no longer
