Reduction processes at the dropping mercury electrode in pulsating fields

Abstract

The work of Breyer and Gutmann on the effect of superimposing alternating fields on the reduction processes occurring at the dropping mercury electrode, has been extended to lead solutions. The work has been done at different frequencies of the alternating field. All the results obtained are interpretable on the basis of the diminution in the overall capacitative impedance of the dropping electrode as the half-wave potential is approached as well as when the frequency of the alternating field increases. These results are largely confirmed by direct observations on phase shifts by means of the oscillograph.
