ELECTRICAL CONDUCTIVITIES, ETC. 



Dissociation Constants Continued. 



141 



These "affinity constants" are of fundamental importance in dealing with organic 

 acids. From these values we learn more about the organic acids as acids than from 

 any other data. The constants are tabulated for convenience of reference, and a 

 glance will give a very good idea of the relative activities of a fairly large number 

 of very different types of the acids of carbon. 



TEMPERATURE COEFFICIENTS IN CONDUCTIVITY UNITS. 



The following tabulation of some of the results will aid in an examination of 

 these values. The heading means zero to the next temperature.
