Abstract
The deposition of silver onto glassy carbon is described. The solution consisted of 10−2 M AgClO4 in 1.0 M HClO4. Experiments reveal the difficulties in trying to separate nucleation and growth phenomena from mass transport effects. A simple semi-quantitative model is proposed to explain the experimental data. It is also shown that the deposition reaction is not completely reversible under certain experimental conditions.
