Submitted by Joanne Stewart / Hope College on Thu, 03/31/2022 - 17:07
Description

This LibreTexts module by Dr. Tom Neils and Dr. Stephanie Schaertel provides a clear and thorough explanation of why some biochemistry and organic chemistry textbooks get the pKa of water wrong. The pKa of water at 25 ºC is 14.0 and not 15.7. This module describes the derivation of the correct value and describes why the value of 15.7 should not be used.
