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.

Values for the negative logarithm of the acid dissociation constant, pKa, of inorganic acids and bases, as well as hydrated metal ions. Definitions of the acid dissociation constant and pKa are given below the table. pK a values given in the table are measuered at 25°C, unless other temperature (°C) is indicated with superscript at the pKa value.

2023年8月30日 · How to use a pKa Table. pKa values have been recorded for a vast variety of compounds and are mainly connected to the molecule’s most acidic functional group. A pKa table simplifies pKa values. A low pKa value (for example, -10) implies a strong acid. A high pKa value (for example, 50) implies a weak acid.
