| Abstract: | A linear correlation between apparent molal volume and osmotic coefficient in aqueous solution is derived for the multiple association process of solute molecules (purine-like compounds). The same correlation has been empirically fitted also by other solutes (urea and urea derivatives) for which aggregation is a matter of debate or may be ruled out. The relation is briefly discussed in terms of the current view on the physicochemical properties of the solvent water. |
