Abstract
A CLOSE study of the surface properties of capillary-active solutions of compounds forming homologous series has shown that the surface activity increases regularly with the molecular weight (Traube's rule). Only aqueous solutions have, however, been thoroughly investigated, and little is known of non-aqueous systems. Since organic solvents have much lower surface tensions than water, the changes produced by solutes will doubtless be much smaller, but the following results show that in certain solvents interesting effects of a similar nature can be observed.
