In the 1880s Wilhelm Ostwald studied the speeds of numerous chemical reactions, including reactions occurring in the presence of acids and bases. In 1894 he revealed what happens: a substance—a catalyst—can affect a chemical reaction’s speed, but is not included in its end-products.
Ironically, Ostwald’s development of the mole concept was directly related to his philosophical opposition to atomic theory, against which he (along with Ernst Mach) was one of the last holdouts. He explained in a conversation with Arnold Sommerfeld that he was convinced by Jean Perrin ’s experiments on Brownian Motion.
The concept was linked to the ideal gas, according to Ostwald. Ironically, Ostwald’s development of the mole concept was directly related to his philosophical opposition to atomic theory, against which he (along with Ernst Mach) was one of the last holdouts.
But probably the discovery for which he is most renowned is the Ostwald Process for manufacture of Nitric acid. The process was pivotal for large scale production of nitrogenous fertilizers. In his later years, Wilhelm studied colour theory and was active in implementation of educational and social reforms.
