ABSTRACT

The vapor liquid equilibria, density, speed of sound, and viscosity of aqueous dipotassium tartrate solutions at T ) (298.15, 308.15, and 318.15) K have been measured. The experimental vapor liquid equilibria data were correlated with the Pitzer equation. The experimental density and speed of sound data for dipotassium tartrate were used to obtain apparent molar volume and apparent molar compressibility values at different temperatures, and these data were satisfactorily fitted to the corresponding Pitzer equations. The limiting apparent molar volume and limiting apparent molar compressibility at each temperature were obtained from the Redlich-Mayer and an abbreviated Pitzer model. The viscosity data were fitted to an empirical equation.
