1 = 2 3 4 5 6 7 8 9 10 11 12 13 14 An analytical chemist is titrating 54.6 mL of a 1.000 M solution of hydrazoic acid (HN2) with a 0.2200M solution of NaOH. The pK, of hydrazoic acid is 4.72. Calculate the pH of the acid solution after the chemist has added 71.7 mL of the NaOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of NaOH solution added. Round your answer to 2 decimal places. il. pH = x $
