Abstract
Ultrasonic velocity of cerium and thorium laurate in benzene-methanol mixture was used to determine the CMC, soap solvent interaction and various acoustic parameters. The results show that ultrasonic velocity, specific acoustic impedance, molar sound velocity increases with increasing soap concentration and decreases with the increase in temperature while intermolecular free length, adiabatic compressibility, apparent molar volume, apparent molar compressibility and solvation number decreases with increase in soap concentration. The internal pressure of the solutions decreases with increase in soap concentration at all temperatures. The results of ultrasonic measurements have been interpreted in the light of well known equations.
