Theoretical Values Of Ultrasonic Velocity Research Articles

Theoretical evaluation of ultrasonic velocity in binary liquid mixtures

Theoretical values of ultrasonic velocity in binary liquid mixtures of propan-1-ol and butan-1-ol with n-hexane, benzene and acetone have been evaluated using Free Length Theory, Collision Factor Theory and Nomoto's relation. Theoretical values are compared with experimental values and the chi-square test for goodness of fit is applied to check the validity of the theories. The theoretical values are in better agreement with experimental values of ultrasonic velocity for alcohols + acetone mixtures compared with alcohols + n-hexane and alcohols + benzene mixtures. The results are discussed in terms of self association in the alcohols.
