CITRIC ACID. 



Column , table 98, shows a well-defined minimum in the molecular 

 m' 



freezing-point lowerings of citric acid. This is seen in the citric acid curve, 

 fig. 5, and in the corrected molecular lowerings for citric acid, L', table 98. 

 Citric acid is another example of a compound that shows neither polymeriza- 

 tion nor hydration in solution. The corrected experimental values in column 

 L' agree closely with the values calculated from the dissociation of the acid 

 as given in column L, table 98. The conductivity curve of citric acid is 

 of the same nature and magnitude as that of the other organic acids which 

 were studied, with the exception of oxalic acid, which has a much larger 

 conductivity.
