François-Marie Raoult

1830–1901 · Physical chemistry

François-Marie Raoult was a French chemist who studied the physical properties of solutions. In 1887 he proposed Raoult's law: the vapour pressure of each component of an ideal solution equals the pure component's vapour pressure times its mole fraction. He showed that a dissolved solute lowers a solvent's vapour pressure in proportion to the amount dissolved, which gave a new way to measure molecular weights and underpins the colligative properties — vapour-pressure lowering, boiling-point elevation, and freezing-point depression — in this section. He was awarded the Davy Medal in 1892.
