TLDR
In this article, the authors interpreted solvent-solute interactions in aqueous solutions of nonelectrolytes using both lattice and distribution function theories of the dissolved state.Abstract:
Solute‐solute interactions in aqueous solutions of nonelectrolytes are interpreted using both lattice and distribution function theories of the dissolved state. Experimental activity data of high precision can be obtained from the literature for aqueous solutions of many nonelectrolytes. If the logarithm of the solvent activity coefficient (γ1) is expressed as a power series in the mole fraction of the solute (x2), lnγ1 = Bx22 + Cx23 + ···, then the coefficients B and C can be determined analytically from the experimental measurements. Values of B were obtained for 52 aqueous mixtures; values of C were obtained for 39 of these mixtures. The solutes considered include aliphatic alcohols, amines, amides, ketones, fatty acids, amino acids, and sugars. In some cases, experimental data were available from which the temperature dependence of the quantities B and C could also be determined. The effect of solute size on the coefficients B and C was investigated using the lattice theories of Flory, Huggins, and Gu...read more

Eugene E. Schrier,R.A. Robinson +1 more
TL;DR: Activity coefficients for each of the components, urea and sodium sulfate, in their ternary mixtures with water have been obtained using the isopiestic vapor pressure method and these results are considered as a model for certain interactions in the denaturation of proteins by electrolytes.

Some factors in the interpretation of protein denaturation.
TL;DR: The chapter reviews that the denaturation is a process in which the spatial arrangement of the polypeptide chains within the molecule is changed from that typical of the native protein to a more disordered arrangement.

Thermodynamics of High Polymer Solutions
TL;DR: In this paper, a statistical treatment of high polymer solutions has been carried out on the basis of an idealized model, originally proposed by Meyer, which is analogous to the one ordinarily assumed in the derivation of the ''ideal'' solution laws for molecules of equal size.

Henry S. Frank,Marjorie W. Evans +1 more
TL;DR: The first and second papers in this series, which make it possible to interpret entropy data in terms of a physical picture, are applied to binary solutions, and equations are derived relating energy and volume changes when a solution is formed to the entropy change for the process as discussed by the authors.
