WebDec 29, 2015 · Solubility Parameter. The solubility parameter δ is a thermodynamic quantity introduced by Hildebrand and Scatchard (HS) to describe the behavior of the so-called regular solutions. Such solutions have a negligible mixing volume and excess entropy of mixing, so that the excess Gibbs free energy coincides with the mixing enthalpy. WebThe solubility parameters and molar volumes of substances can be used, in conjunction with suitable theory, to provide estimates of the thermodynamic properties of solutions; …
