ABSTRACT
Models of mixtures are analytical expressions that, based on molecular concepts, aim to represent the thermodynamic behavior of solutions. As discussed in Chapter 17, the thermodynamic behavior of organic mixtures depends strongly on the nature of the functional groups present and on the length of the hydrocarbon chains of the molecules. The thermodynamic behavior of aqueous mixtures depends on the nature of the solute. A preliminary classification of the nature of organic mixtures helps in deciding what kind of modeling would be appropriate to describe their behavior. Considering Equation 16.12a, https://www.w3.org/1998/Math/MathML"> g θ E = h θ E − T s θ E https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315399065/5df30985-80c1-4e11-9533-10c20ed2604c/content/equ16_12aa.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> we may distinguish two extreme cases.
