Zusammenfassung:Density, surface tension, electric conductivity, and speed of sound of sodium dodecanoate (sodium laurate) aqueous solutions have been determined. Also, isentropic compressibility was calculated. The influence of surfactant concentration and temperature upon these physical properties has also been studied. The experimental values of several physical properties have been employed to determine the critical micellar concentration for this system.
