Electrical double layer at the interface of a Pb electrode with propylene carbonate solutions

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 (E_σ=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 (W_e) on the other hand. It was concluded that Pb electrodes interacted weakly with the molecules of these solvents.
