Feb. 19,1859, Wijk, Sweden - Oct. 2,1927, Stockholm, Sweden). Arrhenius developed the theory of dissociation of electrolytes in solutions that was first formulated in his Ph.D. thesis in 1884 Recherches sur la conductibilit galvanique des dectrolytes (Investigations on the galvanic conductivity of electrolytes). The novelty of this theory was based on the assumption that some molecules can be split into ions in aqueous solutions. The - conductivity of the electrolyte solutions was explained by their ionic composition. In an extension of his ionic theory of electrolytes, Arrhenius proposed definitions for acids and bases as compounds that generate hydrogen ions and hydroxyl ions upon dissociation, respectively (- acid-base theories). For the theory of electrolytes Arrhenius was awarded the Nobel Prize for Chemistry in 1903 [i, ii]. He has popularized the theory of electrolyte dissociation with his textbook on electrochemistry [iv]. Arrhenius worked in the laboratories of -> Boltzmann, L.E., -> Kohlrausch, F.W.G.,- Ostwald, F.W. [v]. See also -> Arrhenius equation.

Part IV deals with the northern European periphery, including the three Scandinavian countries of Sweden, Denmark, and Norway. The chapters in this part describe indifference to the periodic system, much as in France, but for different reasons. Chapter 7 (by Anders Lundgren) explains that a long-standing practical and atheoretical tradition of Swedish chemistry was unaffected by the periodic system, with many new elements discovered by Swedish chemists independently of the system. Because Swedish chemists at the time had little interest in theory, they did not require any explanation of the periodicity of the elements. Nor was the periodic system used as a pedagogical tool for textbooks. Lundgren contends that Mendeleev s periodic system might not have been as important as historians of chemistry have traditionally believed. 

Mendeleev s system has often been considered important for teaching, and his attempts to write a textbook are often taken as the initial step in the chain of thoughts that led to the periodic system. I will therefore start by looking at how textbooks in chemistry in Sweden structured their material, before and after Mendeleev. Thereafter, I will shortly say something about the atheoretical attitude, before going into the system s effects on laboratory work. 

The structure of textbooks, the atheoretical attitude, and the advanced laboratory technique were effected in similar ways to Mendeleev s system they all continued unbroken as they had been carried out before the coming of the system. The periodic system did not change the structure of Swedish textbooks, and in this Sweden was not unique. ...
