A STUDY OF THE PHYSICOCHEMICAL CHARACTERISTICS OF STRONTIUM PALMITATE

The infrared absorption spectrum confirms the ionic nature of strontiu m palmitate. The specific conductane, density, viscosity and ultrasoni c velocity for soap solutions in a solvent mixture of chloroform and p ropylene glycol (70:30, v/v) at 40-degrees are found to increase with increasing soap concentration. The CMC (0 01 M) has been determined. T he values of degree of dissociation for the solutions (.17-0.42) sugge st that the metal soap behaves as a weak electrolyte in solutions. The density results have been explained on the basis of Root's equation w hereas equations of Einstein, Vand, Moulik and Jones-Dole have been fo und to be applicable to these soap solutions The ultrasonic velocity m easurements have been used to study the ion-solvent interactions and t he results satisfactorily conform to the informations obtained from co nductivity, density and viscosity measurements.
