WebWhen you know pH, you can calculate concentration of H 3 O + ions from pH equation. Due to pH = 1, H 3 O + concentration is 0.1 mol dm -3. Due to dibasic acid, when sulfuric acid molecule dissociate, two H 3 O + ions are given. Therefore, concentration of sulfuric acid should be a half of concentration of H 3 O +. WebFor the pH equation, the concentration of hydrogen ions is always a molar concentration, that is, moles of H + per liter. How to calculate pH. If you know the concentration of hydrogen ions, then calculating the pH is just plugging in to the pH equation. Sometimes, a problem will tell you that an acid completely dissociates into ions in solution. mary ellen driscoll https://nhoebra.com
