Excerpt from The Solubility of Liquids in Liquids: The Partition of the Lower Acids Between Water and Cottonseed Oil; Also the Partition of Formic Acid Between Water and Various Organic Compounds That some substances dissolve when brought into contact with various liquids must have been one of the first observations that can be classed as chemical. In the last three decades the study of. Solutions has been the chief occupation of chemists. Yet our knowledge of solutions is still far from adequate and some of our conceptions are still not clear. If we shake a portion of water with oxygen, another por tion with ether, and a third with sugar, assuming constant temperature, equilibria are reached and we call the three solu tions saturated, speaking of the concentrations of the three solutes in the water as their solubilities. The words saturated and solubility are used for all, but actually have quite differ ent meanings in the three cases.
