artifact description
Aqueous solutions of potassium chloride were allowed to flow through air. The solutions were from 10-1 N to 10-7N. The hydrostatic pressure was from 23 to 80 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. A F.P. 54 G. E. tube was used, so the potential difference was measured with essentially no current flow.
