| 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. |
