Abstract

The electrodissolution of a lead rotating disk electrode and the electrodeposition and stripping of lead at a glassy carbon electrode were studied in the 66.7‐33.3 mole percent (m/o) aluminum chloride‐1‐methyl‐3‐ethylimidazolium chloride molten salt at 40°C. The electrodissolution of lead to produce lead(II) is a quasireversible process with an anodic transfer coefficient and a formal heterogeneous rate constant of and , respectively. The electrodeposition of lead on glassy carbon from solutions of exhibits progressive three‐dimensional nucleation with diffusion‐controlled growth of the nuclei. The stripping of lead from this electrode proceeds with 100% efficiency. The formal potential of the Pb2+/Pb couple is , and the diffusion coefficient and Stokes‐Einstein product for lead(II) are and .
