ABSTRACT:
In the present study, ultrasonic velocity (υ), density (ρ), and viscosity (η) have been measured at frequency 1 MHz in the binary mixtures of methyl cobalamine with water in the concentration range (0.1 to 0.0125%) at 303 K and 313 K using a multifrequency ultrasonic interferometer . The measured value of density, ultrasonic velocity, and viscosity have been used to estimate the acoustical parameters, namely adiabatic compressibility (κ), relaxation time (τ), acoustic impedance (z), free length (Lf), free volume (Vf), and internal pressure (Πi),Wada’s constant(W), The obtained results support the complex formation, molecular association by intermolecular hydrogen bonding in the binary liquid mixtures.
Keywords: Methyl cobalamine, free volume, acoustical parameters, ultrasonic velocity.
