WebFeb 5, 2011 · The accuracy of classical theories for predicting gas solubilities in liquids has been examined. The best results are given by the Vilcu–Perisamu equation, which is derived from the Scatchard–Hildebrand theory but takes into account the polarizability of the solute and the permittivity of the solvent. WebIn this work interfacial behavior of Brij S20/P407 and Triton X-100/P407 surfactant mixtures was investigated. The nonideal behavior was elucidated by extending Clint's theory and by determination of the ideal maximum surface excess concentration values.

WebBecause Hildebrand (and Scott, and Scatchard) dealt with a theory where the assumptions were not directly applicable to the real world. Hydrogen bonding and polar solvents were not included since the theory was based on the behaviour of hydrocarbon solvents. As such Hildebrand was dealing with abstract entities rather than real-world solvents.
