SOME SURFACE THERMODYNAMIC QUANTITIES FOR AQUEOUS SOLUTIONS OF ALIPHATIC ALCOHOLS AND FATTY ACIDS

On the basis of the fundamental thermodynamic quantities for the surface phase of the solution, some partial molar surface quantities reflecting the contributions of the surface active solutes have been derived and evaluated. The results show that the thermodynamic surface quantities studied in this paper for the aqueous solutions of both the aliphatic alcohols and acids are nearly identical and exhibit regular changes in each series. The difference between the partial molar entropy for the surface active solute on the surface and that in the bulk has been discussed.
