| Outline of Final Research Achievements |
We carried out theoretical studies of how solvent-induced forces in solution respond to changes in composition or solute molecular size, and obtained a number of highly original results. For example, the well-known but unsolved problem of why the salting-out effect of lithium salts is weaker than that of sodium salts was solved from a molecular theoretical point of view. The relationship between the salting-out effect and salt-induced interactions was derived based on statistical mechanics theory. Unexpected results were also obtained on how the hydrophobic interaction changes with increasing solute molecular size. It was found that the absolute value of the osmotic second virial coefficient increases in proportion to the sixth power of the solute molecular size. This is qualitatively different from the size dependence of the second virial coefficient of gases.
