| Abstract: | The ultrasonic velocity and density measurements of europium soaps in a mixture of benzene and methanol (3:2, vol/vol) were
used to evaluate various acoustic parameters and molar volume and to determine the critical micelle concentration. The results
showed that the ultrasonic velocity, specific acoustic impedance, molar sound velocity, and molar compressibility increase,
and intermolecular free length, adiabatic Compressibility, and relative association decrease with increasing concentration
and chainlength of the soap. The results were interpreted in terms of soap-solvent interaction. |
