Abstract: Ultrasonic velocity, density and viscosity of tryptophan and glycine in aqueous solutions of ZnCl2 as well as CoCl2 have been measured at 303.15 K experimentally. From these experimentally measured values, the apparent molar volume (фv), apparent molar compressibility (фK), viscosity coefficients of Jones-Dole equation and other parameters have been calculated at experimental temperature. These values have been used to explain molecular association, solute-solvent interactions through hydrogen bonding and solvation. The results have been discussed in the light of existing theories of molecular interactions and structural effects on solvent in solution.
