Abstract

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

Abstract

The density and viscosity of the solutions of chromium soaps (myristate, palmitate and stearate) in benzene-methanol (4:l V/V) mixture have been measured at a constant temperature 30 ± 0.05 °C). The density and viscosity results have been explained on the basis of equations proposed by Root, Einstein, Vand, Moulik and Jones-Dole. The values of molar volume obtained by using Einstein's and Vand's equations were found to be in close agreement. The results of Root's and Jones-Dole equation confirm that the soap-soap interactions are almost negligible in dilute solutions. The values of CMC for chromium soaps obtained from density and viscosity measurements were in agreement.
