Ozone Solubilities in Water and Aqueous Salt Solutions

The solubility of ozone in water and in aqueous solutions of sodium chloride, potassium chloride, sodium sulfate, calcium nitrate, and magnesium sulfate has been measured at the temperature 298.2 K. In water and in magnesium sulfate solutions, the ozone solubility has also been studied at temperatures down to 278.2 K. The results were fitted to the previously suggested empirical model of Weisenberger and Schumpe (1996). This enables the estimation of ozone solubilities in mixed aqueous solutions containing up to 50 different ions, even under reactive conditions.
