Abstract
The rate of reduction of Cr+3 at mercury electrodes has been measured polarographically in an extensive series of electrolytes to search for the potential dependence of the transfer coefficient recently reported (2) for this reaction. No clear evidence of such a potential dependence was found and it is concluded that unavoidable propagation of experimental errors coupled with uncertainties in Frumkin double‐layer corrections prevent detection of the predicted potential dependence.
