‘Breaks’ in Interfacial Tension Curves

Abstract

WHEN a single solute is adsorbed from one phase to a water – oil interface, the interfacial tension usually falls in a regular manner with increasing adsorbate concentration, to a limiting value corresponding to a close-packed monomolecular surface layer. In the very few cases1 where exceptions have been found to this rule, the adsorbates have been soaps or similar hydrolysable molecules, and inter-attraction between the long-chain molecules and their products by hydrolysis has been given as explanation of the sharp breaks which occur in the interfacial tension – adsorbate concentration curves.
