Acoustical and Thermodynamical Studies of L-serine, L-glutamine and L-asparagine in Aqueous D-glucose Solutions at 298.15 K

R. Palani and A. Geetha

Abstract: Density (ρ), viscosity (η) and ultrasonic velocity (U) have been measured at 298.15 K in aqueous D-glucose solutions ranging from pure water to 40 mass % of D-glucose. These measurements have been performed to evaluate some important parameters viz. Adiabatic compressibility (β), molar hydration number (n_H), apparent molar compressibility (φ_k) apparent molar volume (φ_V), limiting apparent molar compressibility , limiting apparent molar volume and their constants (S_K, S_V), transfer partial molar volume and viscosity A and B coefficient of Jones-Dole equation. These parameters have been interpreted the molecular interactions in terms of solute-co-solute and solute-solvent interaction present in the given solutions.
