The pka of water and H 3O+ have been experimentally determined to be 14.0 and 0.0, respectively. Earlier values of 15.7 and –1.74, respectively are erroneous numbers proposed by scientists who made some errors in the calculated “rational” values. See: 1) Helv. Chim. Acta 2014, 97, 1. and 2) J. Chem. Educ. 2017, 94, 690.
