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. Web2) The pH of the solution at equivalence point is dependent on the strength of the acid and strength of the base used in the titration. -- For strong acid-strong base titration, pH = 7 at equivalence point -- For weak acid-strong base titration, pH > 7 at equivalence point -- For strong acid-weak base titration, pH < 7 at equivalence point florida battery personal injury lawyerWebWhat is Ethanoic Acid?
