Intermolecular Interaction in the Binary Mixture of valine with Water at 303.15 K

The ultrasonic velocity (u), density (ρ) and viscosity (η) have been measured at 2 MHz frequency in the binary mixtures of valine with water over entire range concentration at 303.15 K using ultrasonic interferometer technique. The experimental data have been used to calculate acoustical parameter namely adiabatic compressibility (βa), acoustic impedance (z), intermolecular free length (Lf) and relative association (RA) with a view to investigate the nature and strength of molecular interaction in the binary liquid mixture. The obtained result support the occurrence of complex formation through intermolecular hydrogen bonding in there binary liquid mixtures and further used to interpret the hydrophilic part of the solute and molecular interactions in the solutions.
