The results of ultrasonic velocity for calcium soap solutions show that the adiabatic compressibility, intermolecular free length and solvation number decrease while the specific acoustic impedence, apparent molal compressibility, apparent molal volume and molar sound velocity increase with increasing soap concentration. The ultrasonic results are in agreement with the conductance measurements and confirm that calcium soaps behave as weak electrolytes in solutions.
