TARTARIC ACID.

There is a well-defined minimum in the molecular lowerings, , of tartaric 



acid. This is seen in table 97 and in fig. 61. The minimum also appears in 

 the column under "Hydrates," table 97, which is the molecular lowerings cor- 

 rected for specific gravities. The corrected molecular lowerings for tartaric 

 acid are very nearly identical with the molecular lowerings calculated from 

 the dissociation, L, table 97. This is true for all of the dilutions studied. 

 Tartaric acid is, then, an example of a compound that undergoes neither 

 polymerization nor hydration in solution. The conductivities of tartaric 

 acid are perfectly normal, as shown by the curve in fig. 63.
