Abstract
Solubilities of oxygen in aqueous sodium sulfate solutions have been measured at an oxygen partial pressure of 1 atm and temperatures of 15, 25 and 35°C by the gas saturation method. The results are not correlated by the empirical Setschenow equation. The estimated solubility of the system at 25°C by the method of van Krevelen et al. is appreciably lower than the observed results. Solubilities of nitrogen in various concentrations of aqueous sodium sulfate and sulfite solutions have been measured at 25°C and nitrogen partial pressure of 1 atm. Solubility of oxygen in aqueous sodium sulfite solutions at 25°C is estimated from the above results. Solubilities of nitrogen and oxygen in aqueous sodium sulfate and sulfite mixed solutions are also discussed.
