Weighing Ions in Solution with the Quartz Crystal

The response of the electrochemical quartz crystal microbalance was studied on gold electrodes in the double-layer region in 0.1 M KOH and CsOH. A shift of frequency of 5-6 Hz is observed which is equivalent to about two layers of oxide. The change of frequency is attributed to the weight of ions in the diffuse-double layer and to an increase of viscosity in the same region.
