Abstract
It is shown by experiment that both types of frequency dependency of the cell impedance, treated in Part I, occur. From the results the diffusion constant of the Hg^++^~2~ ion in 1__M__ HClO~4~ and the reaction rate constant of the zinc amalgam electrode in 1__M__ NaClO~4~ + 10^โ3^M HClO~4~ base electrolyte are calculated. In addition the value of the double layer capacity of the zinc amalgam electrode is reported.
