TABLE 31. 



Conductivity and dissociation of sodium iodide in water, methyl alcohol, and 

 50 per cent methyl alcohol. 



1 It is evident, in this case, that the results are of the same general character as those found for 

 potassium iodide. 



2 Here also, as was found for potassium iodide, the dissociation is greater in the mixture. 



The accompanying measurements were made for potassium bromide in 50 

 per cent methyl alcohol : 



At v = 250 the dissociation is 0.949 for the mixture. 



At v = 256 the dissociation is 0.927 for water, and 0.806 for methyl alcohol, 

 as calculated from Ostwald's l and Carrara's 1 observations. 



The values for the dissociation constants are seen to be about the same as 

 those for potassium iodide. Data for conductivity in aqueous solution could 

 not be found. The values for methyl alcohol are calculated from Carrara's 

 data ; those for the mixture, from the results of Zelinsky and Krapiwin.
