✦ Synopsis

Several electrochemical reactions under ionic mass-transfer rate-control have been studied on cylindrical electrodes forming part of dectrolysis cell. The electrodeposition of copper and the redox reactions for the ferro-ferricyanide systems have been examined, in each case with a large excess of a suitable inert electrolyte. The influences of concentration of the reacting species, rate of flowing, viscosity and diffusivity, height of the working electrode, temperature, and distance between anode and cathode, were studied under streamline-flow conditions. The data are fitted by the dimensionless equation /, 814 Sh = 0.525 eR'la Sc'Js . -* d' 0 d .
