WebThe pKa of water is 14 (at 25 C). It is only in some organic textbooks and a few general chemistry texts that the pKa is given as 15.7. The 15.7 value is the result of a misunderstanding of chemical potential, activity, and standard states, as well as a confusion between Henry's Law and Raoult's law. WebJan 24, 2024 · Understanding the proper use of a pKa table will donate you the ability until recognize which acid-base reactions will happen and which will not.
