To the issue of the relationship between surface tension and electron release work

Earlier, on the basis of the analysis of experimental data on the study of concentration dependences of surface tension and electron release work of binary solutions, the authors of the present work obtained the equations of ST ($\sigma$(x)) and ERW ($\phi$(x)) isotherms describing the experimental isotherms of ST and ERW in the whole concentration range. In the present report, it is shown that the joint analysis of these equations yields a new equation relating the ST to the ERW of a binary solution as a function of composition. However, the latter equation turned out to contain an unknown expression. The introduction of a new concept — the coefficient of sensitivity of ST and ERW of the solution to changes in the composition of the latter, allowed to determine the value of the unknown parameter of the obtained equation through the values determined from the data of experiments. It has been established that ST and ERW are identical in sensitivity to changes in the composition of the solution. It is shown that the obtained formula describes the experiment accurately enough in the whole range of compositions in both solid and liquid states of the binary solution.
