COMPLEX SOLUTIONS. ARCHIBALD.

It will be seen, especially if the above results be plotted, that 

 all three sets of observations agree very well with one another, 

 but that mine agree better with Loomis's than with those of 

 Jones. Their agreement with Loomis's is very close. 



The following table contains the observed and calculated 

 values of the freezing-point depressions for simple solutions, with 

 the differences expresssd as percentages of the observed values. 

 In the calculations Van 't HofF's constant was taken to be 1.86, 

 and the expression used for the depression was 



A = 1.86 (l+2) N/2, 



where N is the concentration of the solution in gr.-equivalents 

 per litre.
