Abstract
The ultrasonic measurements of solutions of terbium soaps (laurate and myristate) in a mixture of 60/40 benzene-methanol (v/v) have been used to evaluate critical micellar concentration (CMC), ultrasonic velocity and various acoustic parameters at 40°C. The results confirm that there is a significant interaction between the soap and solvent molecules. The values of critical micellar concentration (CMC) for terbium laurate and myristate are in agreement with those obtained from other physical parameters. The soap molecules do not aggregate appreciably in dilute soap solution below the critical micellar concentration.
