They attributed this effect to an increase in aggregation with concentration, and noted that very symmetrical molecules showed little deviation from linearity, while very unsymmetrical ones showed large deviations. For the present solutes, the light scattering measurements indicated monodisperse aggregates; in addition, there is apparently little or no correlation between the non-linearity observed here and molecular symmetry. It seems likely that some other effect is responsible for the deviations observed.

The kinetics of the deposition and dissolution of indium (from indium amalgam) in indium sulfate solutions at pH 2.5 have been studied by observing variations of overpotential during individual constant current pulses. The electrode was in the form of a hanging drop of the amalgam, which was renewed for each pulse. The steady-state activation overpotential was reached approximately 1 msec after application of the pulse, which corresponds to a mean value of double layer capacity of 25.4 ~F/cm ~. Plots of the activation overpotential vs. log current density show good Tafel relations in both the cathodic and anodic regions.

In a previous paper the kinetics of the deposition and dissolution of indium was studied by a galvanostatic method of single current pulses. At c.d. higher than 2.5 x 10 -3 amp/cm 2 a change in the mechanism of the deposition and dissolution of indium was observed. To study the phenomenon, the cathodic and ) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.
