In the simplest mixture of two mutually soluble liquids, the volatility of each is undisturbed by the presence of the other. In such a case, the boiling point of a 50-50 mixture, for example would be halfway between the boiling points of the pure substances. For ten points, identify this simple relationship first stated by its eponymous French discoverer.
