VARIATION IN FLUIDITY AND CONDUCTIVITY.

TABLE 42. Comparison of variation in -fluidity and in conductivity. Continued. 



Finally, in table 43 we give a comparison of the temperature coefficients 

 of conductivity for various electrolytes and the temperature coefficients of 

 fluidity for the various mixtures. 



The volumes were 1024 for KI, LiNO 3 , SrI 2 ; 256 for'Nal; 128 for CdI 2 ; 

 256 for Ca(N0 3 ) 2 . 



The temperature coefficients for the ethyl alcohol mixtures are seen to be 

 most nearly equal in the 65 per cent mixture for potassium iodide; for the 

 other salts in the 50 per cent mixture. The temperature coefficients of the 

 mixtures were calculated from Noack's data. 



It is evident from table 43 that for the four salts KI, LiN0 3 , SrI 2 , and 



Ca(N0 3 ) 2 , in most mixtures, the quotient is constant to within 10 per cent 



<P 

 (5 per cent for LiN0 3 ). The same is true for the mixtures of methyl alcohol 



and water.
