Abstract: | The temperature dependence of interface tension in a water-n-hexane system without additives and after addition of stearic acid was experimentally studied at four different concentrations.
A method for determining the excess surface chemical potential from experimental data on the temperature dependence of interfacial
or surface tension is proposed for a diluted solution of surface-active impurity. The excess surface chemical potential of
stearic acid at the interface of a water-n-hexane binary mixture is determined. |
