The thermodynamical behaviour of sodium chloride in aqueous cetyltrimethyl ammonium bromide (CTAB) solution at 303K, 308K and 313K is studied. Density (ρ), viscosity (η) and ultrasonic velocities (U) of the solutions are measured experimentally at different concentrations of sodium chloride. For this, aqueous solutions of CTAB are prepared at three molarities (0.2mM, 0.3mM and 0.4mM). By knowing the experimental values, the internal pressure (πi) and free volume (Vf) of the solutions are determined. From these values quantitative relations between internal pressure, free volume with concentration of these solutions are verified. The results show that sodium chloride existing in aqueous cetyltrimethyl ammonium bromide act as structure-breaker. ∆πi, A, B values of internal pressure, C, D values of free volume and viscosity B-coefficient of Jones-Dole equation are also evaluated to support the present study.
