Studies on Acoustic Behaviour of Samarium Caproate in Alkanols

Abstract
The effects of soap concentration and chainlength of the solvent (alkanols) on the ultrasonic velocity and various acoustic parameters (intermolecular free length, adiabatic compressibility, apparent molal compressibility, specific acoustic impedance, apparent molal volume, molar sound velocity and solvation number) for the solutions of samarium caproate have been investigated. The results have been used to determine the CMC, soap-solvent interaction and solvation number.
