Abstract
In contrast to the polonium method of Schulman and Rideal (Proc. Roy. Soc. (London) Ser. A, 130: 259. 1931) and the "Schwingsonde" method of Yamins and Zisman (Jour. Chem. Physics 1:656. 1933) which determine the surface potential itself, the change of an unknown potential of a monolayer of certain fatty acids is determined by means of a condensor plate system which is fixed at a small distance over the water surface. The decrease of capacity is measured with a Wheatstone bridge and an electronic tube galvanometer.Keywords
