Determination of Critical Micelle Concentration (CMC) of Sodium Stearate Solution in Distilled Water

Abstract

Surfactant is an organic compound having polar and nonpolar parts. The specific conductivity of sodium stearate surfactant in double distilled water has been studied by conductometric method at three temperatures (298.15, 308.15, and 318.15) K. conductivity of the surfactant increases with increase in temperature and concentration of solution. Critical Micelle Concentration (CMC) of sodium stearate was determined attemperature 298.15 K is 0.00095Mol/lit using the easy plot software. FESEM image shows themorphological structure of the sodium stearate surfactant.
