A full explanation would only be given 45 years later, in terms of electrolytic dissociation, by the Swedish chemist Svante Arrhenius.
2.
Electrolytic dissociation of the auxochrome group helps in binding and it is due to this reason a basic substance takes an acidic dye.
3.
Ostwald is especially known for his contributions to the field of electrochemistry, including important studies of the electrical conductivity and electrolytic dissociation of organic acids.
4.
His pressure laws, given general validity by the electrolytic dissociation theory of Arrhenius ( 1884-1887 )-the first foreigner who came to work with him in Amsterdam ( 1888 )-are considered the most comprehensive and important in the realm of natural sciences.
