ELECTRICAL CONDUCTIVITIES, ETC. 



THE DISSOCIATION CONSTANTS. 



The " constants " for the various acids are calculated by means of the Ostvvald dilu- 



_2 



const. This, as is well known, does not apply to the strongly disso- 



tion law, . 

 (1 a)v 



ciated compounds, which therefore have no "constants." The constants are given 



for the volumes 32 and 1024, and for the temperatures 0, 25, and 65.
