Abstract

The isopiestic method was used to determine osmotic coefficients of binary Na<sub>2</sub>Cr<sub>2</sub>O<sub>7</sub>(aq) solutions of concentrations 0.6777-3.8792 mol&nbsp;kg<sup>-1</sup> at 25 °C. The concentration of a saturated binary solution Na<sub>2</sub>Cr<sub>2</sub>O<sub>7</sub>(aq) at 25 °C was determined. The Pitzer ion-interaction model has been used for thermodynamic analysis of the results obtained. Optimum values of the binary parameters of interionic interaction have been calculated and important thermodynamic characteristics of Na<sub>2</sub>Cr<sub>2</sub>O<sub>7</sub>·2&nbsp;H<sub>2</sub>O determined. <p>
