According to Hammett, the strength of a Br�nsted surface site can be determined by the Hammett acidity function,
2.
For example, the Hammett acidity function, " H " 0, has been developed in connection with superacids.
3.
For concentrated solutions of strong acids with a pH less than about zero, the Hammett acidity function is a better measure of acidity than the pH.
4.
:I see what you mean about glacial acetic and the Hammett acidity function ( e . g . ), if the solution is nearly free of water.
5.
He is also known for his research into superacids and his development of a scheme for comparing their acidities based on what is now known as the Hammett acidity function.
6.
Although the Hammett acidity function is the best known acidity function, other acidity functions have been developed by authors such as Arnett, Cox, Katrizky, Yates, and Stevens.
7.
The Hammett acidity function is used in fields such as physical organic chemistry for the study of acid-catalyzed reactions, because some of these reactions use acids in very high concentrations, or even neat ( pure ).
