Solubilities of carbon dioxide, ethylene and acetylene in some aqueous solutions containing a single salt or mixed salts are measured at I atm and 25°C by the gas volumetric method. A method of estimating gas solubility in aqueous solutions of mixed salts from the data of aqueous solutions of each salt is discussed, i.e. an additive rule for salting-out parameters is confirmed and, using this rule, solubility data in such aqueous salt solutions can be estimated from the empirical values proposed by Onda et al.
The estimated results agree well with experimental results within 2.4% as the standard deviation and they are more reliable than those of van Krevelen et al.
