OF CERTAIN ORGANIC ACIDS IN AQUEOUS SOLUTIONS. 63 



3. The conductivity of most organic acids is a parabolic function of 

 the temperature, as has been pointed out by Euler. His formula 



has been shown to hold in every case. 



4. The relative strength of organic acids is not dependent upon the 

 temperature. 



5. " There is no general statement possible concerning the change in 

 dissociation of the organic acids with change in temperature. Maxima 

 occur with several between 25 and 35, while in other cases maxima 

 are indicated at slightly higher temperatures than those at which 

 measurements were made. The dissociation of several acids decreases 

 regularly from 0." 



6. Isomeric acids do not behave similarly with regard to change in 

 their dissociation. 



7. Strong organic acids, as is well known, do not obey the Ostwald 

 dilution law. 



8. The "ortho" and "cis" forms of isomeric acids are the stronger, 

 i. e., have the larger constants. 



9. The migration velocities of the anions are functions of the num- 

 ber of atoms that are present in them. As has already been pointed 

 out in this paper, this fact was made use of in determining the n*> values 

 of dibasic acids. 



10. Most dibasic acids dissociate like monobasic acids. 



11. "The behavior of the organic acids with respect to the change in 

 their dissociation with the temperature, is not in accord with the 

 hypothesis of Thomson-Nernst, which connects dissociating power and 

 dielectric constants; or at least the influence of some other unknown 

 factor is suggested."
