Abstract : The propagation of ultrasonic waves through an ionic solution gives rise to alternating potential differences (ionic vibration potentials) within the solution as a result of differences in the dynamic reactions of the cations and anions to the acoustical waves. The amplitude of the effect is a function of the masses of the solvated ions minus the mass of the free solvent displaced by each ion. Experimental studies were carried out with many electrolytes with particular attention to the elimination of possible false effects. The observed dependence of the ionic vibration potentials on various parameters is in good agreement with theory. From ionic vibration potentials and density data, the absolute values for the ionic partial molal volumes were determined for a number of simple monovalent ions without any assumption as to the value for a given ion or the ratio of values for any pair of ions.
