sented by an equation of this type within the limits of experimental 

 error. In general, it has been found that the more consistent the ex- 

 perimental data are among themselves, the more nearly do they adjust 

 themselves to Equation 11. The results for inorganic electrolytes dis- 

 solved in ammonia are summarized in Table XXVII.

The values of A are not given in this table, but they will be found in 

 Table XXII. By means of the constants in these tables the equivalent 

 conductances of the various electrolytes may be calculated at any de- 

 sired concentration within the limits of experimental error up to approxi- 

 mately normal concentrations. It is obvious that a comparison of the 

 ionization of different electrolytic solutions may be made by means of 

 the constants given above. The relative ionization of two salts will vary 

 as a function of the concentration, since the constants for the two elec- 

 trolytes will not, as a rule, have the same value. The values of the 

 constant K have already been considered and need not be further dis- 

 cussed here. The values of the constant D are seen to lie within fairly 

 narrow limits. Excepting the constants for potassium amides and silver 

 iodide, the values of D lie between 0.127 and 0.62. and most of the 

 values lie between 0.24 and 0.43. There is no fixed relation between the 

 values of D and of K, although in general an electrolyte with a large 

 value of K has a large value of D. Thus, potassium amide, silver iodide 

 and ammonium chloride have the smallest values of K and likewise they 

 have the smallest values of the constant D. So, also, potassium iodide, 

 which has the highest value of the constant K, likewise has the highest 

 value of the constant D. Apparently, the constants K and D are not
