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

Hydrohysteretic Phenomena of “Extremely Diluted Solutions” Induced by Mechanical Treatments: A Calorimetric and Conductometric Study at 25 ∘C
TL;DR: In this paper, the influence of successive dilutions and succussions on the structure of water has been studied, and it is shown that successive dilution and succussion can permanently alter the physico-chemical properties of the aqueous solvent, the extent of which depends on the age of the samples.

Hydrophobic interactions and osmotic second virial coefficients for methanol in water
Lawrence R. Pratt,David Chandler +1 more
TL;DR: In this paper, the second virial coefficient for methanol was calculated and it was shown that the hydrophobic interaction between hard spheres in water is attractive and that its strength diminishes as temperature is raised.

McMillan-Mayer theory of solutions revisited: simplifications and extensions.
TL;DR: This paper restricts ourselves to binary liquid solutions with solute species A and solvent species B and works with a semi-grand canonical ensemble instead of the grand canonical ensemble used by MM, and greatly simplified the derivation of the first MM result.

Structure of membranes and role of lipids therein.
TL;DR: This chapter discusses the structure of membranes and role of lipids therein and phospholipids, important not only to membrane cohesion but also to all forms of transport with the possible exception of simple diffusion.

Ionic liquid-alkane association in dilute solutions
TL;DR: In this article, the entropic change may be consistent with a solvophobic association model of n-alkanes in ionic liquids (ILs) and a simple model is proposed to account for the thermodynamic data.

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.

Free Volume and Entropy in Condensed Systems III. Entropy in Binary Liquid Mixtures; Partial Molal Entropy in Dilute Solutions; Structure and Thermodynamics in Aqueous Electrolytes
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.
