“…E q = 0 ) in acetonitrile not only practically coincides with the magnitude of the difference between their "electrochemical work functions," but is also smaller than the difference between PZC of the Hg and pcSn electrodes in an aqueous solution of a surfaceinactive electrolyte by a mere 0.020 V. This result once again confirms the notion we put forth previously about a weak hydrophilicity of tin. A study of the structure of DEL on the Ga, In-Ga, and Tl-Ga electrodes in eight different solvents shows that the chemisorption interaction between a metal and a solvent at q = 0 increases in the series Tl-Ga < In-Ga < Ga for as long as the metal's work function increases [19]. However, the data that were obtained on a Hg electrode fail to fit this series.…”

“…To perform an analysis of the obtained results, we used the method we developed in our works [17][18][19]. The method is based on an analysis of the charge dependences of values of the difference between reciprocal capacitances of the dense part of DEL on two electrodes = ( ) M1 -( ) M2 .…”

“…The second term in formula (2) reflects the difference between physical interactions of Hg and metal M with the solvent molecules. According to our works [17][18][19], the magnitude of ( + ) chem depends on the nature of metal M, the solvent, and the magnitude of the charge. A chemisorption interaction between a metal and a solvent has a donor-acceptor origin.…”

The structure of the double electric layer (DEL) on a liquid dropping Sn-Ga electrode containing 8 at. % of Sn is studied in acetonitrile (AN) solutions of electrolytes. It is shown that the transition from aqueous to AN solutions of electrolytes makes it possible to expand the region of investigation of parameters of DEL on an Sn-Ga electrode from negative charges to a zero charge and to small positive charges. As follows from the obtained data, throughout the entire interval of charges studied, an excess, as compared with an Hg electrode, chemisorption interaction (Sn-Ga)-AN is absent. It is established that the distance of the closest approach of AN dipoles to an ionic core increases upon going from Hg to Sn-Ga to Ga. The Ga, Bi-Ga, and Sn-Ga electrodes, which possess close values of the "electrochemical work function," are used as an example to show that the metal-solvent chemisorption interaction increases with decreasing distance of the closest approach of its dipoles to the ionic core of the metal. The effect of this factor becomes stronger as the donor number of the solvent increases.
