✦ Synopsis

Pierotti's theory for the solubility of gases in liquids is tested by means of a large amount of literature data on solubility and entropy of solution. The involved solutes comprise the noble gases, mercury vapour, inorganic gases and hydrocarbons up to propane. The involved solvents comprise alkanes, cycloalkanes, nitromethane, polythene, aromatics, dimethylsulfoxide and perfluoromethylcyclohexane.

It appears, that this theory describes the solubilities satisfactory. The description of the entropies of solution is less good.

The enhanced solubilities of BF3, CO,, Cl, and C,H, in some solvents are ascribed to electron donor-acceptor interaction. The association constants for donor-acceptor complex formation are tabulated. _
