“…The obtained results confirmed the choice of Pitzer model as a thermodynamic framework to model this system because of the moderate saturation molality (not exceeding 5 molal) which is in the recommended range of molality well described by Pitzer (around 8 molal). Figure shows the representation of experimental solubility data from several authors, − ,− the recommended data by Clever and Johnston, and the calculated solubility with the Pitzer model.…”

“…In their work, Clever and Johnston were able to collect 46 data points from 14 papers in the temperature range 273.15–373.15 K. To the best of the author’s knowledge, Clever and Johnston’s list of papers − ,− is the most exhaustive on lead nitrate solubility. Later, Payne measured the solubility data of lead nitrate from 293.65 to 341.05 K. The EMF method enables Mikdaze and Makhov to measure the activity coefficient of lead nitrate at 298.15 K from very low concentration to 1 molal and to compare their results with the work of Kielland and Harned and Owen…”

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.
