A comparison of ultrasonic velocity evaluated from Nomoto’s relation, Van Deal-Vangeel ideal mixtures relation, impedance dependence relation and collision factor theories with experimental values have been made in three ternary systems of 1-alkanol with common binary mixture of toluene and dibutylether at 303 K. The relative applicability of these theories to the present systems has been checked and discussed.
