Abstract : Ultrasonic vibration potentials were measured in tetraalkylammonium halides at 220 kHz. The experimental and theoretically predicted values are in good agreement at low concentrations. The concentration dependence can be explained in terms of cation-cation pairs and ion triplets provided the volumes of these aggregates are much less than the sum of the volumes of the separate ions. The partial molal volumes of the tetralkylammonium cations determined from vibration potential measurements are proportional to the cube of their radii as predicted by Hepler's equation with the proportionality constant close to that expected for spherical solute molecules which are large compared to the solvent molecules.
