HYDRATES IN AQUEOUS SOLUTION. 

 TABLE 93. CANE-SUGAR. 



ORGANIC ACIDS. 



The organic acids really belong in the class of the electrolytes. But since 

 they are, generally speaking, weakly dissociated compounds, they have been 

 studied as a class by themselves. Some of these substances contain a small 

 amount of water of crystallization, but, generally, they crystallize either with- 

 out water or with only a small amount. 



Five organic acids have thus far been studied, and the results are given 

 below. The symbols in the tables which follow have precisely the same 

 significance as in the preceding. Organic acids being electrolytes, their 

 conductivities were measured. These are recorded in the tables headed 

 "Conductivity measurements." v is the volume of the solutions, // their 

 molecular conductivities, and a their dissociation. 



ACETIC ACID. 



Acetic acid being soluble in water in all proportions, work was extended 

 to a ten-normal concentration. Although the observed freezing-point lower- 

 ing increased with the concentration, the corrected lowering decreased regu- 

 larly from the most dilute to the most concentrated solution studied.
