The effect on the UV, surface tension, conductance, density and ultrasonic velocity behavior of Sodium dodecyl sulfate (SDS) has been investigated in the presence of different fixed concentrations of 15-crown-5-ether (CE) in order to study the host- guest encapsulation, if any, and the resultant change in the apparent behavior of the inclusion complexes. The apparent and transfer properties including the apparent molal volume VF,s, isentropic compressibility K F,s, have been deduced from the experimental data. The infinite dilution values of VF,s, and K F,s, of the solvated species are also estimated by extrapolation towards infinite dilution. The resulting parameters allow the observation of concomitant reorganizations occurring in the system. Results show that in presence of CE, micellization of SDS is more favorable and there is an overall increase in compressibility of the studied systems.
