Thermoacoustic analysis in binary mixture of pyridoxine hydrochloride with water at 303K

S.P.Dange, O.P.Chimankar

In the present study Ultrasonic velocity (u), density (ñ) and viscosity (ç) have been measured at 2MHz frequency in the binary mixtures of Pyridoxine Hydrochloride with water in the concentration range (0 to 0.1 M) at 3030K using Ultrasonic interferometer technique. The measured value of ultrasonic velocity, density and viscosity have been used to estimate the acoustical parameters namely adiabatic compressibility (âa), relaxation time (ô), acoustic impedance (z), free length (Lf), free volume (Vf) and internal pressure (Pi), with a view to investigate the nature and strength of molecular interaction in the binary mixture of Pyridoxine hydrochloride with water. The obtained result support the occurrence of Complex formationmolecular association through intermolecular hydrogen bonding in the binary liquid mixtures.
