and ordinates, (C,, C, and C,), whose values when substituted 
in equation (7), satisfy this equation. By this method we 
have found k,,C ©, and C,; andk, and k, are easily obtained 
from equations (6). The a’s, the ionization coefficients in the 
k 
mixture, are then determined from the relation, a = a6;

Results of the Calculations. 
The following Table VI contains the results of the calculations 
by expression (5); also the experimental values obtained for the 
depression of the freezing-point of mixtures of solutions of , 
potassium chloride, sodium chloride and hydrochloric aid. The 
results in all the columns are expressed asin Table V.
