WebFeb 13, 2024 · * A note on the pKa of water: The pKa of water is 14. Biochemistry and organic chemistry texts often list the value as 15.7. These texts have incorrectly factored the molar value for the concentration of water into the equilibrium constant. The correct derivation of the equilibrium constant involves the activity of water, which has a value of 1. http://www.scitk.org/subsides/Natural_Science/Chemistry/pKa_table/pKa_table.php john welbourn net worth https://pumaconservatories.com
