Abstract: Conductance values of sodium dodecyl sulphate and dodecyl trimethyl ammonium bromide have been measured in aqueous and 2-propanol+water solutions. The measurements are carried out at 298.15, 308.15 and 318.15 K. From conductivity data the values of critical micelle concentration and counterion association constant () are determined. The observed thermodynamic data reveals that micellisation process is favoured both energetically as well as by entropy gain. 1H NMR data of solutions indicate that whereas 2-propanol is solubilised in the interior of SDS micelles, the penetration of 2-propanol into DTAB micelles is comparatively weak.
