91 



atoms in the molecules of the acids. These curves were drawn for the various 

 temperatures used in the work. 



By placing the dibasic acid in question in its proper position on one of these curves 

 (the position being determined by the number of atoms in its molecule) the n w 

 value for the acid can be read off at once. 



To show how this method works the preceding figure (fig. 5) is given. The 

 dots represent the positions of a number of acids on the curves, the asterisks the 

 positions of a number of dibasic acids, whose n M values were found by this method.
