Abstract

Ultrasonic velocity is one of the important tools for understanding molecular interaction of binary liquid mixtures. Hence, various theoretical models were devised for calculating ultrasonic velocity. In this work, Impedance relation, Nomoto’s Relation, Rao’s specific velocity relation, Van Dael-Vangeel Ideal mixture relation, and Junjie’s relation are considered and the calculated velocities are compared with the experimental values. The theory which gives the closest agreement is analysed and justified. The binary mixtures of octan-1-ol and methyl at 4 different temperaturesover a range of concentrations are considered. A secondary study is also considered to confirm the inferences.
