Description
Summary:The volume changes on mixing of the three binary mixtures, acetone-chloroform, benzene-chloroform, acetone-benzene, and the ternary mixture, acetone-chloroform-benzene, and their molar refractivities and viscosities, were determined.Determinations of total and partial vapor pressures were made. The systems acetone-chloroform and benzene-chloroform show negative deviations from Raoult's law. The system acetone-benzene shows positive deviations.The excess Gibbs free energies of mixing have been calculated for all systems. By combining these data with previously measured heats of mixing (1), the excess entropy has also been calculated. The curves representing zero excess volume, zero heat of mixing, zero excess free energy of mixing, and zero excess viscosity as functions of composition in the ternary system do not coincide. It, therefore, must be concluded that they result from compensating effects and do not represent ideality.
