COMPARISON OF CONDUCTIVITIES. 



61 



there is a shifting towards a mixture containing a greater per cent of alcohol, 

 but the fluidity minimum, so to speak, lags behind the conductivity minimum. 

 For comparison, table 35 is taken from the work of Jones and Lindsay. 



TABLE 35. Comparison of the molecular conductivity of potassium iodide in water, 



methyl alcohol, and mixtures of these solvents. 



It is seen that at the minimum of conductivity occurs in a 50 per cent 

 mixture; the fluidity minimum occurs in a 40 per cent mixture. At 25 

 the minima occur in 65 per cent and 56 per cent mixtures, respectively. 



Strontium iodide also presents a good example of the shifting of the mini- 

 mum, as is shown by table 36, from the work of Jones and Lindsay. 



TABLE 36. Comparison of the molecular conductivity of strontium iodide in water, 

 methyl alcohol, and mixtures of these solvents. 



In the case of strontium iodide the real minimum would probably be found 

 in a mixture between the 50 and 75 per cent mixtures. So, also, in the case 

 of lithium nitrate, as is shown in table 37, taken from the work of Jones and 

 Lindsay.
