Abstract
Abstract In this work, we report density, viscosity, refractive index and water activity data for the aqueous trisodium citrate (C6H5Na3O7) system at 298.15 K. The parameters of the Pitzer ion-interaction model are evaluated from isopiestic water activity data. The apparent molar volume at infinite dilution was calculated from density data and a new value for the conventional partial molar volume of citrate ion (Cit3−) was derived. The experimental viscosity data have been fitted to the Kumar equation. Using this equation, the hydration number (h) and ion–solvent interaction parameter (B) for trisodium citrate were obtained.
