Description :
Various parameters such as Ultrasonic Velocity, density, viscosity have been measured experimentally for the solution of leaf extract of TridaxProcumbens in 50% ethanol with various concentrations at 298.15 K, 303.15 K, 308.15 K keeping constant frequency of 4 MHz.The intermolecular free length decreases with decrease of temperature and hence the close packing of molecules which in effect decreases the sound velocity. From these experimental data the acoustical parameters such as adiabatic compressibility, intermolecular free length, acoustic impedance, relative association have been computed.The acoustical parameters like adiabatic compressibility, intermolecular free length, relative association, relaxation time, specific acoustic impedence prove to be more useful to predict and confirm the molecular interactions. These parameters are useful to predict the magnitude of molecular interactions taking place in the solution.
