In this paper we report new density and viscosity data of L-serine and L-valine in aqueous NaCl solutions as a function of amino acids molality at fixed salt concentration (0.1, 0.2, 0.5, 0.7 and 1.0 mol.kg(-1)) and temperature T = (293.15, 298.15, 303.15, 308.15, 313.15, 318.15 and 323.15) K at atmospheric pressure of p = 0.1 MPa. From density, some derived properties such as the apparent molar volume, V-phi, limiting partial molar volume, V-phi(0), and expansibility, E-phi(0), standard molar volume of transfer, Delta V-phi(0), and hydration number, n(H), were calculated and discussed in terms of solute-solvent interactions and structural effects. The Jones-Dole equation and transition state treatment were used to obtain the viscosity B coefficient, free energy of activation of viscous flow per mole of solvent, Delta mu(0#)(1), and per mole of solute, Delta mu(0#)(2), entropies, Delta S-2(0#) and enthalpies, Delta H-2(0#), of activation of viscous flow for amino acids. All the activation parameters were discussed in terms of transition state theory. The co-sphere overlap model was used to interpret the results. The structure making/breaking ability of the amino acids in solutions was also discussed. (C) 2020 Elsevier Ltd.
