Svante August Arrhenius
1859-1927
Swedish physical chemist who developed the theory of electrolytic dissociation of molecules in solution. His theory explained the phenomena observed when certain substances dissolve; he proposed that they break up into electrically charged positive and negative ions.
He applied this theory to acids and bases, arguing that acids dissociate to produce H+ ions and bases OH– ions. The Arrhenius equation resulted from his generalization of the effect of temperature on the rate of chemical reactions. He received the 1903 Nobel Prize in chemistry.
