Acoustical Parameters of Binary Mixture of Pyridine and Carbon Tetrachloride

The acoustical properties of a mixture of pyridine with CCl₄ have been carried out by ultrasonic technique at room temperature. The experimental data was used for the calculation of inter-molecular adiabatic compressibility, acoustic impedance and inter molecular free path length. The different type of molecular interactions in the mixture have also been discussed in the context of obtained acoustical parameters. Moreover, the change in the value of acoustic impedance with mole fractions of non-polar compound conclude that the interactions between dissimilar molecules are significant. It is also concluded that these interactions have a correlation with the polarizability of molecules in the compound mixture.
