WebMay 6, 2024 · The pH scale usually ranges from 0 to 14. Aqueous solutions at 25°C with a pH less than 7 are acidic, while those with a pH greater than 7 are basic or alkaline. A pH level of 7.0 at 25°C is defined as "neutral" because the concentration of H 3 O + equals the concentration of OH − in pure water. WebIn other words, at a high concentration, e.g. 1 mol/L = 100, pH = 0 (ACIDIC) at a low concentration, e.g. 10-14 mol/L, pH = 14 (ALKALINE) Hence, different substances are objectively compared with each other, where pH 0 is extremely acidic, pH 14 extremely alkaline, and pH 7 neutral. In the last few years the measuring of pH has gained in ...
