“…As an example, Frazer and Myrick (in interaction parameters, n ij . We will investigate this model 1916) (32), in their work with aqueous sucrose solutions, with data obtained for high concentrated IgG in physiologic suggested that the free solvent in solution exhibits near ideal solution. The observed osmotic pressure data are also fitted behavior, provided that hydration and association are consid-to the virial expansion model based on mass concentration ered in determining the effective free-solvent concentration.…”
