WebJun 14, 2024 · p H is a logarithmic function of [ H 3 O +]: (10.11.1) p H = − log [ H 3 O +] p H is usually (but not always) between 0 and 14. Knowing the dependence of p H on [ H 3 O +], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic.
