ULTRASONIC VELOCITIES IN BINARY MIXTURES

Abstract

Ultrasonic velocities and their variation with concentration have been measured for five binary mixtures, e.g., toluene-heptane, pyridineaceticacid, pyridine-n-butyric acid, nitrobenzene-n-butyl alcohol andmethyl alcohol-benzene. From the observed value of the velocity,adiabatic compressibility was calculated for each mixture. The effect of compound formation and association on the compressibilities of these mixtures has been examined.
