文摘

The density (蟻), viscosity (畏), refractive index (n_D), and speed of sound (u) of glycine, l-alanine, and l-valine have been determined in different mass fractions (w₁ = 0.01, 0.03, 0.05) aqueous barium chloride solutions at 298.15 K. The limiting apparent molar volumes (_V⁰), experimental slopes (S_V^*) have been found out from the Masson equation. A and B coefficients have been obtained from the Jones鈥揇ole equation. The Lorentz鈥揕orenz equation has been employed to measure molar refractions (R). Limiting apparent molar adiabatic compressibilities (_K⁰) of the studied amino acids at infinite dilution have also been measured. These derived parameters have been used to explore solute鈥搒olute and solute鈥搒olvent interactions in the solutions.
