Surface tension of binary system

The surface tension reflects the nature of chemical bonds between species of the system under question. Since molten salts are ionic in character, the surface tension is predominantly given by the chemical nature of the present ionic species. Due to different coulombic interactions between species, the ions more covalent in character are concentrated on the surface and become surface active. Therefore the concentration dependency of the surface tension of binary systems will be substantially influenced by the ionic composition. Due to the equilibrium between the bulk and the surface, the course of the... 

Booth and coworkers also studied the surface tension of binary systems (dicar-boxylic acids (oxalic, malonic, succinic, glutaric, and adipic acids) and ammonium sulfate) both experimentally (at 21 °C) and using modeling to determine whether additive or thermodynamic surface tension models agreed better with experimental data [190]. Following the methodology of Topping et al. [143] they found that the LiLu model best predicted binary systems.
