DISCONTINUITIES IN THE SURFACE STRUCTURE OF ALCOHOL-WATER MIXTURES,

Abstract

Interpretations vary regarding relationships between surface tension and concentrations of binary liquid solutions. These interpretations are based upon a scanty number of observations and do not take into account the possibility that the mutual molecular arrangement of the components on the surface may tend to follow some particular patterns, which undergo modifications at certain critical compositions of the liquids. Surface tension determinations were obtained by the capillary rise method for two systems: methyl alcohol-water, and ethyl alcohol-water, at 25C, throughout the whole range of concentrations, with over 80 experimental points obtained for each system. Plots of the Langmuir isotherm confirmed the validity of the proposed conjecture. The plots of the MeOH-H2O and EtOH-H2O consist of twelve and eleven rectilinear segments, respectively. A detailed interpretation of the data is presented.
