The Hammett function calculates a related quantity to this value when this is too extreme for conventional means.  This quantity is related to pKa and the log of two related quantities via the Henderson-Hasselbalch equation, and along with changing temperature, changes in this value can denature proteins.  Defined as the negative logarithm of the concentration of hydrogen ions, for 10 points, name this scale, ranging from zero to fourteen, for which water has a value of seven.
