Using the Brock and Bird relation and the Flory statistical theory, the surface tension of five binary mixtures of 1,1,2,2-tetrachloroethane with benzene, toluene, p-xylcne, acetone and cyclohexane have been evaluated at 298-15 K. The values of surface tension thus obtained have been utilized to compute ultrasonic velocity via the Auerbach relation. Theoretical values have been compared with experimental data and deviations in the ultrasonic velocity have been interpreted in terms of intermolecular interactions. Indian Academy of Sciences.
