“…The data available in the chemical literature were evaluated with the purpose to find all the experimental data involving lead nitrate aqueous solutions. As noticed earlier in previous work, nitrate salt data belonging to metal nitrate are less abundant in the open literature. Concerning lead nitrate, the only available source of experimental data of the osmotic coefficient comes from Robinson and Stokes, and the reported data in the Russian compilation by Mikulin was the same set going from 0.1 to 2 molal at 298.15 K.…”

A comprehensive thermodynamic model was elaborated for lead nitrate aqueous solution using the Pitzer framework. The evaluation of the ion interaction parameters for the Pitzer model was carried out using the osmotic coefficient of lead nitrate aqueous solutions collected from the open literature at 298.15 K and also saturated vapor pressure from 283.15 to 373.15 K. A temperature dependency form of Pitzer parameters was selected after several tests of different Pitzer parameter sets. The chosen set of parameters was able to cover wider temperature ranges and consequently calculate system properties from dilution to saturation in the temperature range of 273.15–373.15 K. An equation for the solubility product for lead nitrate was also proposed, leading to the prediction of solubility data for this system. The temperature dependency of the Pitzer model shows a satisfactory behavior, giving the possibility of using the model to predict the thermodynamic properties. The extrapolation capacity of the model was also tested at temperature above 373.15 K.

The freezing depression points of aqueous phosphoric acid have been determined using a method based on measurement of solution conductivity. The osmotic coefficient for freezing point lowering was calculated by the condition of solid-liquid equilibrium and by the equation proposed by Bjerrum (1918). A calculation method is presented in this study to evaluate the ion interaction parameters for the Pitzer model from freezing point and isopiestic molalities of aqueous phosphoric acid solution. The model of Chen, Bromely and the Three-Characteristic Parameter Correlation (TCPC) are also used to model this system. The isopiestic molality values from literature data are used to optimize these models. Using these parameters, we were able to estimate thermodynamic properties: osmotic coefficient, mean activity coefficient and water activity for the H 3 PO 4-H 2 O system, and contribution to a better understanding of the thermodynamic behaviour of the aqueous system containing phosphoric acid.
