Theoretical evaluation of ultrasonic velocities in binary liquid mixtures at different temperatures

Bhavani M.D., Ratnakar A., Kavitha Ch.

Vol. 5

1-6

Ultrasonic velocities calculated from various theories and relations like Nomoto's relation, Van dael ideal mixing relation, Impedance relation, Rao's specific velocity relation and Jungie's theory are compared with experimental values in binary liquid mixtures o-anisidine with o-cresol at temperatures 303.15, 308.15, 313.15 and 318.15 K over the entire mole fraction range. The relative applicability of these theories to the present system is checked and discussed. A good agreement is observed between experimental and theoretical values. The results are explained in the light of molecular interactions occuring in these mixtures.
