Abstract

Aqueous solutions of potassium chloride were allowed to flow through air. The solutions were from 10-1 N. to 10-7 N. The hydrostatic pressure was from 17 to 22 cm. of solution. The flow was vertical and laminar, through a circular aperture in a thin platinum disc on to a second platinum disc. The diameter of the aperture was 0.05 cm. The discs served as electrodes. The potential difference was measured with a vacuum tube potentiometer. The floating grid method was used, so the potential difference was measured with essentially no current flow. The values obtained were similar to existing data on the streaming potential of such solutions through glass tubes and through cellulose diaphragms.
