Abstract
The isopiestic method was used to determine osmotic coefficients of binary Na2Cr2O7(aq) solutions of concentrations 0.6777-3.8792 mol kg(-1) at 25 deg rees C. The concentration of a saturated binary solution Na2Cr2O7(aq) at 25 degrees C was determined. The Pizter ion-interaction model has been used f or thermodynamic analysis of the results obtained. Optimum values of the bi nary parameters of interionic interaction have been calculated and importan t thermodynamic characteristics of Na2Cr2O7. H2O determined.
