Viscometric Investigations on Chromium Soaps in Benzene-Methanol Mixture

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.
