A Study of the Initial Stages of Co Deposition on a Silver Electrode in Ammonia Medium Using an Electrochemical Quartz Crystal Microbalance

<table>A comparison of two cyclic voltammetric curves obtained in the Ag/<i>x </i>M Co(II)+1 M (NH<sub>4</sub>)<sub>2</sub>SO<sub>4</sub> (pH 9.3) system at two different Co(II) concentrations, (a) <i>x </i>= 0 and (b) <i>x </i>= 1 mM. The scan potential rate was of 5 mV s<sup>−1</sup>, and the potential interval was −100 mV and −990 mV. In the inset an amplification of the region comprising the peak of the alleged underpotential deposition is shown.</table>
