Abstract

A technique for the measurement of quartz supported electrode oscillation frequency with special reference to transient electrochemical experiments was prepared. Due to changes in solution viscosity and density and in surface roughness during potential step experiments, the error in calculation of mass changes from frequency responses can reach 3–5 %. Initial deviation of electron numbers from unity by 30–60% during pulse electroreduction of dicyanoargentate shows that this process is not a simple faradaic reaction.
