Ultrasonic, volumetric and transport studies of molecular interaction of some amino acids in aqueous dextrose solutions at 303.15 K


R Palani, B Dhivyabharathi, K Devanathan

Apparent molar compressibilities (φk) and apparent molar volume (φv) of L-serine and L-alanine in aqueous and aqueous solutions of dextrose at different concentrations have been determined at 303.15K from precise density, ultrasonic velocity and time flow measurements. From these data limiting apparent molar compressibilities (φko), limiting apparent molar volumes (φvo), and their constants (Sk, Sv), viscosity A & B-coefficients and the corresponding transfer parameters (Δφko and Δφvo ), and hydration numbers (nH) have been calculated. The results are interpreted in terms of solute-solute and solute-solvent interaction in these systems. It has also been observed that L-alanine act as a more structure maker than L-serine.
