When a battery is connected between two electrodes immersed in an electrolyte, the phenomenon known as polarization occurs. This polarization limits the electric current which will flow through the electrolyte for a given potential difference. As is well known to those familiar with the method of chemical analysis known as polarography, the degree of polarization and consequent current flow through the electrolyte is a function not only of the chemical composition of the electrolyte, but also of the amount of agitation, either thermal or mechanical, which the electrolyte experiences. In this paper, an apparatus is described which allows investigation of the flow patterns resulting when low‐frequency sound in liquid passes through small orifices.
