Apparent molar volumes and transport behavior of glycine and l-valine in aqueous solutions of tripotassium citrate at TÂ =Â (308.15 and 318.15)Â K

► The viscosity data have been analyzed by Jones-Dole equation. ► Activation parameters have been obtained to throw light on the mechanism of viscous flow. ► The partial molar volumes of transfer at infinite dilution have also been calculated. ► Transfer volume data have been used to calculate the pair and triplet interactions. ► Solute-solute, solute-solvent interactions and structural changes of solutes in solutions are discussed.
