Solubility prediction of n-fatty alcohols and sterols in complexing and non-complexing solvents according to the mobile order theory
Article Abstract:
Volume fraction solubilities of some solid n-fatty alcohols and sterols are predicted in neat organic polar, nonpolar and hydrogen-bonded solvents. Water is included. The predictions, in the context of the mobile order thermodynamics, are based on melting properties of the alcohols, on molar size, and on group interaction stability constants. A proposed thermodynamic solubility model from the mobile order theory in H-bonded liquids is an advance in the direction of good estimates of solubilizing capacity of common solvents for nonideal complexing systems, the solid alcohols.

Thermodynamics of dissolving gaseous argon in different solvents
Article Abstract:
Cavity creation within the solvent, an excluded volume effect, impedes the solubility of gaseous argon. Larger Gibbs energy changes are seen with the solvent hydrazine than with water, and qualitatively different enthalpies are present in the dissolution of argon in these two solvents. Structural reorganization of water upon introduction of argon accounts for the hydrophobicity of this hydrocarbon.

Salt effect on the solubility of mer-(+)-tris (L-alaninato) cobalt (III)
Article Abstract:
The effect of various salts on the solubility of mer-(+)-tris (L-alaninato) cobalt (III) is presented. The aqueous solubility of nonelectrolytes decreases as inorganic salts are added, a phenomenon called salting out. This was true in this case for NaF, CH3COONH4, and NaH2PO4, but NaCl, NaBr, NaI, and NaNO3 caused an increase in solubility, or salting in.
