A theory is presented of the complex behaviour of the streaming zinc amalgam electrode in a Zns+ solution. It is assumed that the Znp+/Zn+ and the Zn+/Zn(Hg) electrode reactions occur at potentials where at the dropping amalgam electrode the Zna+-resp. Zn-concentration at the electrode surface is vi

Abstract
The anomalous behaviour of the Tl^+^/Tl(Hg) electrode in 1 KNO~3~ + 0.1 M KCl solution has been studied experimentally applying the theory described in parts IV and VI of this series. It is shown that this anomaly can be explained assuming that the double layer capacity increases on adding thallous ions. The increase ฮ C appears to be proportional to the TI^+^ concentration. The phase angle ฮฆ of the faradaic impedance is equal to ฯ/4.

## Abstract It is shown both by calculation and experimentally that in a galvanic cell with two plane electrodes, through which an alternating current flows, the concentration waves interfere if the distance of the electrodes is of the order of a wave length.
