Ozone solubilities in water and aqueous salt solutions

The solubility of ozone in water and in aqueous solutions of sodium chlorid e, potassium chloride, sodium sulfate, calcium nitrate, and magnesium sulfa te has been measured at the temperature 298.2 K. In water and in magnesium sulfate solutions, the ozone solubility has also been studied at temperatur es down to 278.2 K. The results were fitted to the previously suggested emp irical model of Weisenberger and Schumpe (1996). This enables the estimatio n of ozone solubilities in mixed aqueous solutions containing up to 50 diff erent ions, even under reactive conditions.
