Abstract Electromotive force measurements were carried out on the system KCl−KNO3−H2O at constant total ionic strengths of 0.5, 1.0, 2.0 and 3.0 mol-kg−1 and at 25, 35 and 45°C using a cell consisting of a potassium ionselective electrode and a Ag/AgCl electrode. The Harned coefficients and the Pitzer binary and ternary interaction parameters for the system have been evaluated at each temperature. The osmotic coefficients, excess free energies of mixing and heats of mixing of the system have been predicted at each of the experimental temperatures and ionic strengths. The solubility data at 25°C are also interpreted.
