Abstract
The Bowden-Kideal1 electrolytic method of measuring area by the electrodeposition of hydrogen ions on conducting surfaces has been modified so that rapid measurements may be made by using audio-frequency alternating currents superposed on very feeble direct currents, and measuring directly the alternating changes of electrode potential with an amplifier and wave analyser with one megohm input impedance. Comparisons of surface areas were made by measuring the alternating current required to give the same alternating electrode potential as on one square centimetre of a mercury surface.
