Abstract
Aqueous solutions of the sodium and potassium salts of the higher fatty acids i.e. aqueous soap solutions, exhibit a number of unique properties, quite different from those of most ordinary salt solutions. Aside from the familiar properties of these soap solutions, such as their opalescence, their detergent action, and their ability to froth, they exhibit somewhat abnormal osmotic properties, conductivities, viscosities, surface tensions, adsorptive powers, etc.
Since it is the long hydrocarbon chain which is undoubtedly responsible for the characteristic properties of colloidal electrolytes, and since the low solubility of the pure fatty acids in water prevents a study of aqueous solutions of these substances, it was decided to investigate the properties of some of the pure fatty acids in a better solvent. By analogy, from the work of Norris on cetyl sulphonic acid, cited above, solutions of the pure fatty acids in an appropriate solvent might be expected to exhibit some of the properties of aqueous soap solutions. The solvent chosen for such a study was acetic acid.
