Question

An analytical chemist is titrating 199.7 mL of a 0.4800 M solution of hydrazoic acid (HN₃ ) with a 0.7400 M solution of NaOH. The p K_a of hydrazoic acid is 4.72. Calculate the pH of the acid solution after the chemist has added 60.87 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 solution added. Round your answer to decimal places.

Round your answer to 2 decimal places.
