TL;DR: In this article, the critical micelle concentration (CMC), soap-solvent interaction, and apparent molar volume of copper soap have been investigated at constant temperature using ultrasonic measurements.
Abstract: Copper soaps have been prepared from fresh and used sesame oils. The formation of copper soaps has been confirmed by spectral technique. Micellar characterization of copper soaps has been studied by density, viscosity and ultrasonic measurements. The apparent molar volume and apparent molar compressibility have been enumerated at constant temperature using these data. The results were used to determine the critical micelle concentration (CMC), soap-solvent interaction. The results of apparent molar volume were discussed in terms of Masson's equation and the results of viscosity data have been discussed in terms of Jones-Dole equation. The CMC values are found to increase with decrease in average molecular weight of the soap. It has been observed that there is a decrease in soap-solvent interaction with the decrease in average molecular weight of copper soap.
