Theoretical values of ultrasonic velocity in binary liquid mixtures of ethyl benzoate + 2- methyl -1- propanol, ethyl benzoate + 2-butanol and ethyl benzoate + 2- methyl -2- propanol have been evaluated at 303.15,308.15, 313.15 and 318.15K using Nomoto’s relation, ideal mixing r elation (IMR) impedance dependence relation (IDR), Rao’s velocity method (RVM) and Junjie’s method (JM). The relative merits of these theoretical relations wer e examined by comparing the theoretical values of ultrasonic v elocity with the values obtained experimentally. Th e validity of the theories was checked by applying the chi-square test for goodness of fit and by calculating the av erage percentage error (APE).
