Abstract
Abstract The relation between limiting partial specific compressibility, \barκ20, and solvation of solute was reviewed and determination of \barκ20 was carried out in different types of solutions; ideal binary mixtures, such as benzene–toluene, and suspension systems of polystyrene latex and colloidal silica. In ideal mixture and polystyrene latex systems, the partial specific compressibility and limiting partial specific volume of each solute were equal to the corresponding value of the solute itself. The \barκ20 of the colloidal silica decreased from a positive to negative value with increasing pH of the media, showing strong hydration in alkaline solution.
