Aqueous sulfuric acid is an important chemical not only for the industry but also to the environment. A need for a simple thermodynamic model is obvious.
The thermodynamic properties of aqueous sulfuric acid were modelled with the Pitzer equation. Both the second dissociation constant K2 for sulfuric acid and Pitzer parameters were fitted simultaneously. After variation of the experimental data used and the temperature dependency of the Pitzer parameters, it was found that only four parameters with eight terms can describe the thermodynamic properties of aqueous sulfuric acid over a temperature range of 0-170°C.
The thermodynamic properties obtained are in good agreement with literature values as well as with other Pitzer based thermo- dynamic models for aqueous sulfuric acid.
The recent version of Pitzer equation, NPL Pitzer, was also tested, It was found to accurately predict activity and osmotic. Fine. Item #4797
