VAN'T HOFF, J.H. - "VAN'T HOFF'S LAWS"

L'Équilibre Chimique dans les Systèmes gazeux ou Dissous à L'État dilué.

Harlem, Les Heritieres Loosjes, 1886. With orig. printed frontwrapper to vol. XX. In "Archives Néerlandaises des Science Exactes et Naturelles.", Tome XX., 3. issue. Pp. 171-302 (=3. issue). Van't Hoff's paper: pp. 239-302. Clean and fine.

First appearance of an importent paper in which Van't Hoff "showed from quantitative experiments on osmosis that dilute solutions of cane sugar obey the laws of Boyle, Gay-Lussac, and particularly leading to an extension of Avogadros law. He here announced the laws which bears his name and which apply to ideal solutions "solutions which are diluted to such an extent that they are comparable to ideal gases." Einstein in 1905 and later made importent applications of these laws.

"Thus van't Hoff was able to prove that the laws of thermodynamics are valid not only for gases but also for dilute solutuions. His pressure law gave general validity to the electrolytic theory of Arrhenius,,,consequently van't Hoff became an adherent of the theory of electrolytic dissociation."(DSB XIII, p. 579. In 1901 Van't Hoff was the first to receive the Nobel Prize for chemistry.
