Acoustical and Excess Parameters in Binary Liquid Mixture at Temperature 303.15 K
Acoustical and excess parameters have been calculated from the experimentally measured data of ultrasonic velocity, density and viscosity in binary liquid mixtures containing herbal extract of drug Piper Nigrum with ZnCl2 over the composition range (number of moles (n) of drug = 0.7009, 1.4018, 2.1027, 2.8036 and 3.5045) at 303.15 K temperature. Obtained results are fitted to the Redlich - Kister polynomial equation. These results have been explained on the basis of the intermolecular interactions present in the liquid mixtures. Present investigation provides important information about the physiological system and used to understand the mechanism of their metabolism in the living system.
