WebpH of the dilute solution can then be calculated using the "pH formula": pH = -log 10 [H +(aq)] [H +(aq)] = concentration of hydrogen ions in solution in mol L -1 As an aqueous solution of acid is diluted with water at 25°C its pH approaches 7 When an aqueous solution of a weak acid is diluted, the resultant solution has: WebExplain why ethanoic acid and hydrochloric acid of the same concentrations would give different pH readings. An acid is defined as a proton donor-the hydrogen ion (H +) dissociates from the acid in a solution. Hydrocholoric acid is a strong acid-all of the acid molecules will release their protons into a solution, making it very acidic.
