Theoretical values of ultrasonic velocity in four ternary liquid mixtures
of 1-propanol, 1-butanol, 1-pentanol and 1-hexanol with TEA in n-hexane
for different proportions have been evaluated using Nomoto`s Relation,
Ideal Mixture Relation, Free Length Theory and Impedence Dependance 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.
