 25 all trace of a minimum has disappeared. 



In order to see the connection existing between the conducting power of 

 the solutions in the various solvents, the preceding table is given for the sake 

 of comparison.

 FIG. 2. POTASSIUM IODIDE AT 0. 



Some of the values in table 9 are plotted in fig. 2. It is seen that the 

 values of the molecular conductivity reach a minimum in a mixture of 

 methyl alcohol and water containing 50 per cent methyl alcohol. It is also 

 seen that an addition of approximately 10 per cent of alcohol lowers the 

 conductivity of the aqueous solutions to that of an alcoholic solution.
