WebbOn this scale, pure H 2 SO 4 (18.4 M) has a H 0 value of −12, and pyrosulfuric acid has H 0 ~ −15. Take note that the Hammett acidity function clearly avoids water in its equation. It is a generalization of the pH scale—in a dilute aqueous solution (where B is H 2 O), pH is very nearly equal to H 0.
