Additivity of adiabatic compressibility with the size and geometry of the solute molecule

It was shown for dilute aqueous solutions of few homologous series of organic non-electrolytes that the effect of solutes on compressibility decrease is directly linked to the length of their molecules and the groups, which are their constituents. The contributions of the groups - constituents of solute molecules - have been determined and discussed. It seems possible now to predict compressibility of aqueous solutions of organic non-electrolytes only from their structural formulae. (c) 2007 Elsevier B.V All rights reserved.
