An analytical chemist is titrating 64.6 mL of a 0.8000 M solution of nitrous acid (HNO₂) with a 0.7600 M solution of KOH. The pK of nitrous acid is 3.35. Calculate the pH of the acid solution after the chemist has added 53.9 mL of the KOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of KOH solution added. Round your answer to 2 decimal places. pH = 0 X
