The thermodynamic research on the systems involves fundamental research in solution chemistry. The measurements of emf are performed to calculate the activity coefficient of HBr in the electrolyte mixtures at 250C. These measurements are carried out at different ionic strengths ranging from I=0.01 to 3.0 mol●kg-1. The applications of these data are in the fields of (a) geochemistry, (b) geological systems, and (c) hydrometallurgy. Experimental data have been treated by using Harned equations as well as the Pitzer ion-interaction theory including higher order electrostatic effects. The results will be compared with those of transitional metals and lanthanide salts.

Application of Pitzer ion-interaction treatment for thermodynamics of HBr + KBr + H2O, HBr + NiBr2 + H2O and HBr + GdBr3 + H2O systems at 250C
