Volumetric, compressibility and transport behaviour of some α-amino acids in water and aqueous glycerine at 303.15 K

Abstract

Density (p), viscosity (η) and ultrasonic velocity (U) have been measured for L-glutamine, L-asparagine and L-lysine in water and aqueous glycerine (0, 0.5 and I mol dm- 3 ) at 303.15 K. 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 (ϕ K 0 ), limiting apparent molar volume (ϕ v 0 ) and their constants (S K , S v ), transfer volume (Δϕ v 0) and viscosity A and B coefficients of Jones-Dole equation. The results have been discussed in terms of solute-co-solute and ion-solvent interaction.
