Abstract
Displacement rates were measured by rotating cylinders of zinc and copper in silver nitrate solutions for short time intervals, followed by analysis of the solutions for silver ion content. At concentrations of a few hundredths molar silver nitrate, the rates are several times as great as calculated for normal diffusion or transport control, because of local cell electrolytic currents. This is analogous to previous results with similar systems. To minimize silver deposition and local cell action, very low silver ion concentrations ( , ) were also used, with radioactive Ag110 as tracer for the analysis. In these solutions the rates approach values calculated for normal transport control.Keywords
