Anionic surfactants, Sodium Stearate (SS), Potassium Stearate(PS), Sodium Oleate(SO) and Sodium Lauryl Sulphate(SLS) in binary alcohol-water solvent systems of varying composition have been studied at various mole fractions of the salts at various temperatures through conductivity measurements. The CMC value of anionic surfactants is seen to be increased with the rising of temperatures in alcohols-water systems. Thermodynamic parameters Enthalpy (∆H˚m), Entropy (∆S˚m) and Free energy (∆G˚m) of micellization of anionic surfactants Sodium Stearate, Potassium Stearate, Sodium Oleate and Sodium Lauryl Sulphate have been determined in the varying composition of alcohol-water solvent systems at 303 K, 308 K, 313 K and 318 K. Different thermodynamic parameters have been reported.

Anionic surfactants, thermodynamic parameters, Critical micelle concentration (CMC); Conductivity (k).
