Book Description

Excerpt from The Electrical Conductivity of Non-Aqueous Solutions Van't Hoff formulated his modern theory of solutions from the results of Pfeffer's classic experiments on the osmotic pressure of a few substances in aqueous solutions, and from the work of de Vries 3 who pointed out that equimolecular quantities of dissolved substances produce the same osmotic pressure. Van't Hoff' stated that the condition of a substance in the gaseous state is analogous to the condition in which a substance exists in dilute solutions wherein the osmotic pres sure of the dissolved substance corresponds to the pressure of the gaseous particles. It was soon observed, ahowever, that many substances did not give normal values for the osmotic pressure, the rise of the boiling, or lowering of the freezing point; and thus that the laws of gases would not hold for solu tions of these substances.
