Abstract: Ultrasonic velocity and density of ammonium soaps in 2-propanol have been measured at different temperatures (308-323K). Using these data, critical micelle concentration (CMC), adiabatic compressibility, apparent molar compressibility, molar sound velocity, molar sound compressibility, specific acoustic impedance, relative association constant, solvation number and apparent molar volume have been evaluated. These parameters show a change at CMC suggesting the micellar behaviour of soaps. The effect of temperature on these parameters has also been studied.
