TL;DR: In this article, the pKa values for protonated amines in pyridine were derived from the curves of titrations carried out with a calibrated glass electrode and homconjugation constants were estimated from the titration curves.

TL;DR: In this paper, a glass electrode was calibrated by means of some compounds with dissociation constants known from conductivity measurements, and the value 2·10−19 was found for the self-dissociation constant of m-cresol.

TL;DR: In this paper, the authors determined the dissociation constant of water in pyridine from titration of some acids with known dissociation constants with tetramethylammonium hydroxide.
