Abstract
Theoretical values of ultrasonic velocity in the binary mixtures of cyclohexanone with 2-propanol and 2-methyl-2-propanol have been evaluated at 303 K using Nomoto’s relation, collision factor theory, free length theory, ideal mixture relation, Junjie’s method. Theoretical values are compared with the experimental values and the validity of the theories are checked by applying the chi-square test for goodness of fit and by calculating the average percentage error (APE).
Highlights
Measurement of ultrasonic velocity gives the valuable information about the physicochemical behaviour of the liquid and liquid mixtures
Semi-empirical formula and theories are available for the theoretical computation of ultrasonic velocity in liquid and liquid mixtures[1,2,3,4,5]
The experimental values along with the values calculated theoretically using Nomoto’s relation, collision factor theory, free length theory, ideal mixture relation and Junjie’s method for the systems: (i) cyclohexanone + 2-propanol and (ii) cyclohexanone + 2-methyl2-propanol at 303 K are given in Table 1& 2 respectively
Summary
Measurement of ultrasonic velocity gives the valuable information about the physicochemical behaviour of the liquid and liquid mixtures. Semi-empirical formula and theories are available for the theoretical computation of ultrasonic velocity in liquid and liquid mixtures[1,2,3,4,5]. The best suitable theory for the given molecular system under study is picked out by calculating the average percentage error and chi-square test at 1% and 5% levels.
