WebJan 30, 2024 · Although pH is formally defined in terms of activities, it is often estimated using free proton or hydronium concentration: pH ≈ − log[H3O +] or pH ≈ − log[H +] Ka, the acid ionization constant, is the equilibrium constant for chemical reactions involving weak acids in aqueous solution. WebFrequently people confuse pH with acidity—pH is the scale on which acidity is expressed, but it is not synonymous with acidity. An appropriate way to compare the acidity at two different pH values is to express the relative percentage change of the H + concentration at the two pH levels, as in Figure 2.
