The critical micelle concentration, degree of dissociation and dissociation constant of calcium caprylate in mixtures of varying composition of chlorofoME-propylene glycol were determined using conductometric measurements. The results show that the soap behaves as a weak electrolyte in these solutions below the CMC. The value of the specific conductance increases by the addition of dye to these soap solutions.Keywords

Ultrasonic velocity of cerium and thorium laurate in benzene-methanol mixture was used to determine the CMC, soap solvent interaction and various acoustic parameters. The results show that ultrasonic velocity, specific acoustic impedance, molar sound velocity increases with increasing soap concentration and decreases with the increase in temperature while intermolecular free length, adiabatic compressibility, apparent molar volume, apparent molar compressibility and solvation number decreases with increase in soap concentration. The internal pressure of the solutions decreases with increase in soap concentration at all temperatures. The results of ultrasonic measurements have been interpreted in the light of well known equations.Keywords
