ACETIC ACID. 



Ill 



The corrected lowering found experimentally, was less than the theoretical 

 lowering at all concentrations except the most dilute. This shows that 

 acetic acid in water is polymerized, and that the amount of the polymeri- 

 zation is greater the more concentrated the solution. This is exactly in 

 accord with what was pointed out earlier by Jones and Murray,* in their 

 investigation on the effect of one associated liquid on the association of an- 

 other associated liquid. They showed that water an associated liquid- 

 diminishes the association of acetic acid, which is also a strongly associated 

 liquid, and that the magnitude of this effect is a function of the amount of 

 water relative to the amount of acetic acid present. The more concentrated 

 the solution of acetic acid, the greater will be the complexity of its molecules. 

 A few of the freezing-point data for acetic acid are plotted in fig. 62. The 

 conductivities of acetic acid are perfectly normal and are plotted in fig. 63. 



Acetic acid shows no evidence of the formation of hydrates except, possibly, 

 in the most dilute solution studied.
