A chemist titrates 70.0 mL of a 0.1144M nitrous acid (HNO, solution with 0.2245 M NaOH solution at 25 °C. Calculate the pH at equivalence. The p K 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.
