On the influence of electrolytes on the 

 diffusion of non-electrolytes. 



By 

 L. W. Öholm. 



In a previous work ^) the author has presented the results 

 of an investigation concerning the influence of non-electro- 

 lytes on the diffusion and electric conductivity of electrolytes. 

 The measurements which simultaneously were carried out 

 as to the viscosity of these water solutions, containing 

 electrolytes and non-electrolytes, considerably helped to 

 explain the course of both the diffusion and the conductivity. 

 Each appeard to depend not only on the quantities of the 

 substanses in the solution but also on the nature of the 

 electroljiies and non-electrolytes. 



The determinations of the viscosity showed that of the 

 salts in question KCl, added to a solution containing a non- 

 electrolyte, for instance cane sugar or glycerine, always 

 lessened the inner friction. LiCl had a contrary effect, the 

 friction being thereby increased. Of these viscosity con- 

 ditions the inference could a priori be drawn that the mole- 

 cules of a non-electrolyte are more movable in a /\C/-solution 

 than in pure water, and that consequently the råte of their
