concordant results with solutions of greater dilution than those 

 above. It is seen, however, that the ratio appears to reach a 

 constant value in these dilute solutions, and the writer has 

 assumed that the value of this ratio for the solution of concen- 

 tration .0001 of the salts and .001 of the acid would hold for 

 infinite dilution. 



Table II gives the values of the specific molecular conductivi- 

 ties at infinite dilution for obtained from Kohlrausch's values 

 at 18 by aid of the above ratios. The conductivities are 

 expressed as in Table I. 



TABLE II. 



Determination of the lonization Coefficients at 0C. for 

 Simple Solutions. 



For this purpose the specific conductivities at 9 C. for series 

 of simple solutions of each electrolyte were found. These conduc- 

 tivity values are also necessary for the drawing of the curves 

 showing the relation between the concentration and the conduc- 

 tivity ; these curves being required in the determination of the 

 ionization coefficients in the mixtures. 



Table III contains the observed values and also the ioniza- 

 tion coefficients calculated therewith. The concentrations are 

 expressed in gramme-molecules per litre at 0C., and the 

 conductivity in terms of 10~ 4 times Kohlrausch's new unit.
