Question 3 of 3 questions about the titration of 10.00 mL of 0.1600 M histamine (C5H9N3, a weak base with pKa = 6.72; pKa is NOT a typo) with 0.2000 M HI. Continuing the titration: an additional 2.00 mL HI solution is added (total addition of HI is 10.00 mL). What is the pH after this addition? Do not type units. Do not use units.
