An analytical chemist is titrating 102.2 mL of a 0.5200M solution of nitrous acid (HNO,) with a 0.5400M solution of KOH. The p K of nitrous acid is 3.35. Calculate the pH of the acid solution after the chemist has added 21.31 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.
