WEBMar 7, 2024 · In most general chemistry textbooks, the pK a of water at 25 ºC is listed as 14.0. In many organic chemistry textbooks and some biochemistry texts, however, the pKa of water at 25ºC is listed as 15.7. This module describes the derivation of these two values and describes why the value of 15.7 should not be used.

WEBSo these electrons would come off onto the oxygen, so the electrons in magenta come off onto the oxygen, and those would be these electrons right here, to form water as our conjugate base. So H3O+ has a higher pKa value than H-Cl, therefore H3O+ is not as strong of an acid, or we could say it the other way around.
