2. 20.0 mL of 0.1000 M Benzoic Acid (HC7H5O2) in a flask is being titrated with 0.1000 M NaOH contained in a burette. Show clearly by calculations the final pH at the end of each of scenario. (ka = 6.4 x 10 5) 1. When no NaOH was added to the acid in the flask. 2. The Burette was filled with 0.1000M HCI for titration by mistake and this was realized after 5.0 mL of the HCI was dispensed in to Benzoic Acid in flask. 3. The contents in the flask were not changed but the Burette was cleaned, filled with 0.1000 M NaOH and 15.0 ml of 0.1M NaOH was dispensed into flask. 4. What if 25.0 mL of 0.1000 M NAOH was dispensed in scenario 3 instead of 15.0 mL into flask? 5. What if 27.0 mL of 0.1000M NaOH was dispensed in scenario 3 instead of 25.0 mL into flask?
