| Abstract: | The ultrasonic velocity and density measurements of lanthanum and cerium soaps in a mixture of 60 % benzene and 40 % methanol (v/v) were used to evaluate various acoustic and thermodynamic parameters and to determine the CMC. The results were interpreted in terms of soap-solvent interaction. |
| Keywords: | Ultrasonic velocity La- andCe-soaps compressibility acoustic impedance sound velocity solvation number soap solvent interactions lcritical micelle concentration |
