Abstract: The capacitance of the electrical double layer was measured in situ on a renewable Pb electrode in solutions of Bu4NClO4 in propylene carbonate (PC). The results and published data were analyzed using correlational relationships between the zero charge potentials (Eσ=0) of Hg, Pb, Sn, and Ga electrodes in solutions of surface-inactive electrolytes in PC, acetonitrile, and water on the one hand and the electron work functions of these metals (We) on the other hand. It was concluded that Pb electrodes interacted weakly with the molecules of these solvents.

Keywords: mechanically renewable Pb electrode, propylene carbonate, impedance method, surface-inactive electrolyte, electrical double layer (EDL), model description.
