The classical work of McBain on the electrical conductivity and other properties of aqueous solutions of the soaps led him to postulate the formation of the ionic micelle. This aggregate of ions has a greater mobility than that of the ions composing it, and its formation accounts for the characteristic increase in conductivity exhibited by colloidal electrolytes. The conception has resulted in great advance in the study of all classes of colloidal electrolytes e. g ., protein and gelatine salts, dyes, and other substances of high molecular weight.
