Abstract

Ultrasonic velocity is measured at 2MHz frequency in the binary mixtures of Ethyl Benzoate with 1-Propanol, 1-Butanol, 1-Pentanol and theoretical values of ultrasonic velocity have been evaluated at 303K using Nomoto's relation, Impedance relation, Ideal mixture relation, Junjie's method and free length theory. Theoretical values are compared with the experimental values and the validity of the theories is checked by applying the chi-square test for goodness of fit and by calculating the average percentage error (APE). A good agreement has been found between experimental and Nomoto’s ultrasonic velocity.

Highlights

Measurement of ultrasonic velocity gives the valuable information about the physicochemical behavior 1, 2 of the liquid and liquid mixtures
Semiempirical formulas and theories are available for the theoretical computation of ultrasonic velocity in liquid and liquid mixtures[3,4,5,6,7]
In continuation of our dielectric work[8,9,10] we report the ultrasonic velocity evaluated using Nomoto’s relation[3], Impedance relation[4], Ideal mixture relation[5], Junjie’s method[6] and free length theory[7] for the binary mixtures of Ethyl benzoate with 1-Propanol, 1-Butanol, 1-Pentanol
