Abstract: Ultrasonic measurements on lithium myristate and palmitate have been carried out in a mixture of 50% benzene and 50% methanol (v/v) to determine the critical micellar concentration (CMC), soap solvent interaction and various acoustic and thermodynamic parameters. The results show that the ultrasonic velocity, specific acoustic impedance, molar compressibility, apparent molar compressibility, relative association and Rao's number increase while the adiabatic compressibility, intermolecular free length, apparent molar volume, solvation number and available volume decrease with increase in soap concentration. The results of ultrasonic measurements have also been explained in terms of well known equations.
