TABLE 10. Molecular conductivity of ammonium bromide. 



We see that in these results we have practically the same phenomenon as 

 in the case of potassium iodide. In the case of ammonium bromide the 

 minimum point in the conductivity values appears to be reached with an 

 alcohol of 50 per cent.

TABLE 12. Comparison of the molecular conductivity of ammonium bromide. 



1 Here also a 50 per cent ethyl alcohol gives a minimum, but only in the case of the more dilute 

 solutions, namely, for dilutions t> = 512 and 1024. 



2 In this comparison there is no trace of a minimum, nor does there appear to be a probability of a 

 minimum for any mixture of methyl and ethyl alcohols.
