Abstract: Ultrasonic measurements of strontium soaps (caprate, laurate and myristate) have been carried out in a mixture of chloroform and propylene glycol (70%-30% v/v) to determine the critical micellar concentration (CMC), soap-solvent interaction and various acoustic parameters. The results show that ultrasonic velocity, intermolecular free length, adiabatic compressibility, adiabatic molar volume and apparent molar compressibility decrease while specific acoustic impedance, relative association and solvation number increase with increase in soap concentration. The results of ultrasonic measurements have also been explained in terms of well known equations.
