Does a weak acid have a high pH? – Sage-Answer

WebFeb 13, 2024 · Since the concentration of the weak acid is much higher, even though it only dissociates partially, it produces more H+ ions than the strong acid, leading to a lower pH. At equal concentrations, a strong acid will typically have a lower pH than a weak acid, since the strong one will donate more protons to the solution. WebWorking out the pH of a strong acid. Suppose you had to work out the pH of 0.1 mol dm-3 hydrochloric acid. All you have to do is work out the concentration of the hydrogen ions in the solution, and then use your calculator to convert it to a pH. With strong acids this is easy.

WebReading the pH scale. The pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution.
