Metal Chlorides

It has been shown by Evans (1937) that the effects of the alkali metal chlorides at a hexane-water interface are markedly similar to the effects of the same salts on the surface tension of water as determined by Heydweiller (1910) and Schwenker (1931), i.e. the tension apparently increases steadily with concentration. Hence, from the Gibbs adsorption principle, the salt is negatively adsorbed throughout. The recent work of Jones and Ray (1937) has, however, demonstrated that the surface tension of the salt solutions examined by them first decreases with increase of concentration, passes through a minimum and subsequently increases beyond the value possessed by pure water. On general grounds it would be expected that phenomena similar to those observed by Jones and Ray at the free surface should likewise be exhibited at an interface. In an attempt to investigate this point interfacial tension data have been obtained for the interface dekalin ( trans -decahydro- naphthalene)/water, using salts of various valence type.

Temperature Ranges

The surface tensions of methanol, acetone, dimethylformamide, dimethylsulfoxide, and methylamine over limited temperature ranges, and of solutions of alkali halides in the first three of these liquids at 25 °C have been measured by the method of maximum bubble pressure, with precautions against moisture. The data for the pure liquids are compared with literature data where these exist. The results for the solutions are discussed in the light of various existing theories.
