“…The experimental data for Mn(NO 3 ) 2 by Jones et al 19 are in good agreement with our measurements regardless that their values were measured under a total pressure of 0.35 MPa, while all our measurement were done in prevailing atmospheric pressure. According to this correlation, we can confirm that the effect of pressure over narrow pressure ranges is minor in the measurement of volumetric properties of electrolyte solutions.…”

The apparent molal volumes of selected metal nitrate salts, Al(NO 3 ) 3 , Fe(NO 3 ) 3 , and Mn(NO 3 ) 2 , in water have been assessed from the available density measurements of their aqueous solutions at 25 °C over a wide molality range. The values of ϕ V have been fitted to the Pitzer model using its volumetric contributions. The model parameters β (0)V , β (1)V , C φV , and V̅ 0 were determined for each aqueous electrolyte, over the composition range from 0 to about 3.5 mol•kg −1 H 2 O. The new experimental data and parameters obtained will be useful to extend the present database of electrolyte solutions as well as its application areas, allowing management of many physical properties of aqueous solutions in a numerical way in various end-uses.

“…Inspection of the results in figures 9 and 11 also illustrate the increasing uncertainties C p,/ at low m, as noted in the earlier discussion of equation (2) and figure 1. Figure 12 shows the differences in aqueous apparent molar heat capacities DC p,/ between a series of seven divalent metal ion nitrates and magnesium nitrate [12,35,39,55]. These results illustrate the approximate differences in the specific contributions of the divalent metal ions to C p,/ (T, p = 0.35 MPa, m) in an aqueous matrix of nitrate ions.…”

A Pitzer Parametrization To Predict Solution Properties and Salt Solubility in the H–Na–K–Ca–Mg–NO₃–H₂O System at 298.15 K

et al. 2018

A new set of Pitzer interaction parameters is proposed to describe the excess properties of the H−Na−K−Ca−Mg−NO 3 − H 2 O system at 298.15 K. From these parameters we reproduce the osmotic coefficient, mean activity coefficients, and density for the binary systems, and also salt solubility in the ternary subsystems. The binary interaction parameters are either selected from the literature or redetermined in this study. In the case of KNO 3 −H 2 O and HNO 3 − H 2 O binary systems, partial electrolyte dissociation has to be taken into account to represent accurately all the experimental data up to very high concentrations. Then solubility data of salts in the corresponding ternary systems are used to determine the ternary interaction parameters and the solubility products of the double salts. As KNO 3 and HNO 3 are partially dissociated, we have determined new interaction parameters involving neutral species (for instance η KNO 3 /Na + /H + or μ HNO 3 /KNO 3 /Na + ) to draw the phase diagram of quaternary systems Na−K−H−NO 3 . To complement the study, we also propose a set of volumetric Pitzer interaction parameters for all the binary systems and for the H−K−NO 3 ternary system, so solution density can be computed at 298.15 K.
