Abstract
The equilibrium properties of the H2O-HNO3-N2O5 system is represented using the MSA electrolyte activity model developed by Ball et al [1]. As our purpose is to obtain a good representation of both VLE data and the liquid phase composition, the data base used to adjust the parame ters includes VLE experimental values and also data relative to real s pecies concentrations, deduced from Raman spectroscopy measurements, s ome of them being obtained during the present study. The quality of th e representation compares well with the experimental deviations.
