A comparison of square-wave voltammetry models to determine the number of electrons exchanged in metal deposition

A comparison of square-wave voltammetry models for calculating the number of electrons exchanged in a metal deposition reaction. Experiments were conducted for silver deposition on platinum in an aqueous HNO3 solution and for nickel and lanthanum deposition on platinum in molten LiCl. Diffusion coefficients for Ni2+ and La3+ in LiCl at 700 degrees C are calculated. Accuracy of soluble-soluble models versus a soluble-insoluble model is discussed. A simple method for determining the number of electrons exchanged under the constraint of well-compensated ohmic drop is proposed and evaluated.
