BY MIXTURES OF ELECTROLYTES.—BARNES. 151 
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 IT gives the values of the specific molecular conductivi- 
ties at infinite dilution for 0° obtained from Kohlrausch’s values 
at 18° by aid of the above ratios. The conductivities are 
expressed as in Table I.

Determination of the Ionization Coefficients at O°C. for 
Simple Solutions. 
For this purpose the specitic conductivities at 0°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 0°C., and the 
conductivity in terms of 10~* times Kohlrausch’s new unit.
