Study of Transport Properties of Tris (hydroxymethyl)aminomethane Hydrochloride in 20% (v/v) Acetone-Water System at

Viscometric properties of Tris-(hydroxymethyl)amino methane hydrochloride are measured in 20% (v/v) acetone-water system 303.15°K. The related parameters are the experimental values of viscosity ( ) allow to determine relative viscosity ( ), viscosity -coefficient of the Jones-Dole equation, free energies of activation of viscous flow and per mole solvent, and solute, respectively. The excess molar volume, excess viscosity, excess Gibb’s free energy, and interaction parameter of Grunberg and Nissan have also been calculated. These studies are of great help in characterizing the structure and properties of solutions. The addition of an organic solvent to water brings about a sharp change in the solvation of ions. 1. Introduction The density is one of the key thermodynamic properties of electrolyte solutions and belongs with an equilibrium property, while the viscosity is one of the key transport properties of electrolyte solutions and belongs with a dynamic state property. Both of them rein dispensable basic data to engineering design and process optimization. Knowledge of viscometric properties studied in binary solvent system is useful for engineering design of new applications. Viscosities are important physico-chemical parameters widely studied in aqueous, aqueous-organic, and others [1]. The density and viscosity are important basic data used in chemical engineering designs, solution theory, and molecular thermodynamics [2]. Physicochemical processes of electrolyte solutions are of considerable interest due to their importance in numerous industrial processes. Extensive experimental viscosity data are available for mixed-solvent system. In mixed-solvent electrolyte solutions, viscosity is affected by the concentration of electrolytes but also by the composition of the solvent. Even the viscosity of solvent mixtures may show a complex behavior and change significantly with composition. The knowledge of physico-chemical properties of liquid mixtures of two or more components are of theoretical and industrial importance due to their wide range of applicability as solvent media in various physico-chemical processes. In the present investigation following parameters are measured by Viscosity data of tris (hydroxymethyl)aminomethane hydrochloride is measured in 20%？(v/v) acetone-water system 303.15°K is used to determine -coefficient ( ) and constant characteristic of ion-ion interactions excess viscosity , and excess molar free energy of activation of flow . The interaction parameters Gruenberg and Nissan ( ) were also calculated and reported. The
