Effect of Salt on the Micellar Behavior of Dysprosium Soap

The critical micelle concentration (CMC), specific conductance, molar conductance and free energy of dysprosium soap in methanol and in a mixture of water methanol in the presence of salts were determined using conductometric measurements. The result show that dysprosium soaps behave as weak electrolytes in dilute solutions. The critical micelle concentration (CMC) was found to decrease with increasing ionic radii of counterions.
