CONDUCTIVITY AND VISCOSITY IN MIXED SOLVENTS. 



Kahlenberg and Lincoln l studied solutions of ferric chloride, antimony tri- 

 chloride, bismuth trichloride, and mercuric chloride in phosphorus trichlo- 

 ride and arsenic trichloride, with results which confirm those mentioned 

 above. Centnerszwer 2 is authority for placing cyanogen among the solvents 

 that do not dissociate. Frankland and Farmer 3 have also shown that 

 nitrogen peroxide does not dissociate, while Skilling 4 demonstrates that solu- 

 tions in hydrogen sulphide show no conductivity. 



The following table of inorganic solvents is given to show what relations 

 exist between dissociating power, dielectric constants, and the association 

 factor : 



TABLE 1. Inorganic solvents which effect dissociation. 



The values for the association factors are taken from the researches of 

 Ramsay and Shields, 5 and Ramsay and Aston; 6 while those for the dielectric 

 constants are almost wholly taken from the work of Turner. 7
