A chemist titrates 230.0 mL of a 0.0532M nitrous acid (HNO_2) solution with 0.2981 M NaOH solution at 25 degree C, calculate the pH at equivalence. The pK_a of nitrous acid is 3.35. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of NaOH solution added.
