PROPERTIES OF ELECTRICALLY CONDUCTING SYSTEMS 



dielectric constant and the constants m, D, and K for electrolytes in 

 different solvents. So far as possible, typical electrolytes have been 

 chosen, since, as we have seen, the constants are in general a function of 

 the electrolyte. We have seen, however, that the typical electrolytes be- 

 have similarly in a given solvent, so that a rough comparison may be 

 made between the dielectric constant and the various constants which 

 determine the form of the conductance function. Those values of D 

 which appear in parentheses have been calculated from the values of P, 

 assuming that the value of A is proportional to the fluidity of the 

 solvent. This relation is not strictly true, particularly in the case of the 

 inorganic solvents. However, it unquestionably gives the order of mag- 

 nitude of this constant.

The solvents are arranged in the order of their dielectric constants. 

 It will be observed, in the first place, that the constant D is in all cases 

 of the same order, varying between 0.2 and 0.69 with a mean value in the
