PROPERTIES OF ELECTRICALLY CONDUCTING SYSTEMS 



this type is generally applicable to solutions of electrolytes in various 

 solvents. Since a larger amount of experimental material is available 

 for solutions in liquid ammonia than for solutions in any other solvent, 

 we may consider solutions in this solvent first. Since the more dilute 

 solutions have already been considered and found to conform to the

mass^action law as a limiting form, it follows that the equation will be 

 applicable to the more dilute solutions in any case. It remains, there- 

 fore, to determine whether the equation likewise applies to the more 

 concentrated solutions. 



Kraus and Bray, 6 who have examined the applicability of this equa- 

 tion to a large number of non-aqueous solutions, including solutions in 

 ammonia, have concluded that the experimental values may be repre-
