Arrhenius, Lehrbuch der kosmischen Physik (Leipzig, 1903); (3) A.
SVANTE AUGUST ARRHENIUS (1859-), Swedish physicist and chemist, was born on the 19th of February 1859, at Schloss Wijk, near Upsala.
Arrhenius is specially associated with the development of the theory of electrolytic dissociation, and his great paper on the subject, Recherches sur la conductibilite galvanique des electrolytes - (1) conductibilite galvanique des solutions aqueuses extremement diluees, (2) theorie chimique des electrolytes, was presented to the Stockholm Academy of Sciences in 1883.
In 1887 Svante Arrhenius, professor of physics at Stockholm, put forward a new theory which supposed that the freedom of the opposite ions from each other was not a mere momentary freedom at the instants of molecular collision, but a more or less permanent freedom, the ions moving independently of each other through the liquid.
The evidence which led Arrhenius to this conclusion was based on van 't Hoff's work on the osmotic pressure of solutions (see Solution).
