PDF-Titration Lab

Name Purpose To calculate the molarity of an acid by titrating it with a base of known molarity The following acid base reaction will take place HClaq NaOHaq. Learning Goal 25 Calculate the pH at any point, including the equivalence point, in an acid-base titration. At the equivalence point, the pH = 7.00 for strong acid-strong base titrations. However, in A Physician’s perspective. Navin K Jain, MD. CONFLICT OF INTEREST. None to disclose. OBJECTIVES. Learn PAP titration protocols. Learn current practices in PAP titration.
