and ordinates, (C lt C 3 and C 3 ), whose values when substituted 

 in equation (7), satisfy this equation. By this method we 

 have found k l , C C 3 and C 3 ; and k^ and k 3 are easily obtained 

 from equations (6). The a', the ionization coefficients in the 



k 

 mixture, are then determined from the relation, a = ~ 



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 as in Table V.
