Conductivity of Aqueous Solutions. Part IV. 



We have reduced his results to 100 by means of our temperature-coeffi- 

 cients at that temperature, and have given them beside our own in the 

 table. It will be seen that the results with silver nitrate are widely diver- 

 gent at all concentrations, and that those with magnesium sulphate are 

 somewhat so except at the higher concentrations, indicating the difficulty 

 of getting reliable results at such high temperatures in glass vessels.

42. CHANGE OF THE EQUIVALENT CONDUCTANCE WITH THE 



CONCENTRATION. 



The empirical law of the variation of the conductance of silver nitrate, 

 potassium sulphate, and barium nitrate with the concentration is shown by 

 table 24, in which the values of the exponent n in the function 

 C(A A) K{C\.) n are tabulated.
