Abstract

The acoustical parameters of glycine have been measured in aqueous solutions of sodium benzoate(SB), sodium bromide (SBr), and nicotinamide (N) at 298.15K. The molar sound velocity (R), molar compressibility (W), Free length (Lf), free volume (Vf), internal pressure (πi), relaxation time (τ), ultrasonic attenuation (α/f2), and van der Waals constant (b) values have been calculated from the experimental data. These parameters are used to discuss the molecular interactions in the solutions.
