HYDROCHLORIC ACID. 



Having investigated a fairly large number of salts, some of the more 

 common acids were then studied, and the freezing-point lowerings produced 

 by solutions as concentrated as could be used, measured with the thermom- 

 eters at our disposal. Dilutions ranging from 6 N to 0.05 N were employed. 

 In very dilute solutions hydrochloric acid does not seem to have the power 

 of combining with water. The amount of combined water increases with 

 the concentration from about 0.3 N to the most concentrated solution that 

 was studied (see curve, fig. 56). A possible explanation of the fact that, 

 in dilute solutions, hydrochloric acid does not combine with water at all 

 is given under the general discussion.
