Viscosity Behavior of α-Amino Acids in Acetate Salt Solutions at Temperatures (303.15 to 323.15) K

Abstract

Viscosities of l-lysine monohydrochloride, l-histidine, and l-arginine in 1 m (mol · kg−1) aqueous solutions of sodium acetate, potassium acetate, and calcium acetate salts has been determined at (303.15, 308.15, 313.15, 318.15, and 323.15) K. The Falkenhagen coefficient, A, and Jones–Dole coefficient, B, relative viscosity, and specific viscosity of the solutions have also been determined using the measured viscosities. The results are interpreted in terms of solute–solute and solute–solvent interactions occurring in the system under investigation and also discussed in terms of the structure-making/breaking ability of the solute in these salt solutions. The structure making/breaking abilities of the solutes in the studied systems are strongly influenced by temperature.
