A 27.46 mL solution of weak acid is titrated with 0.0859 M NaOH. It requires 75.15 mL of the NaOH titrant to reach the equivalence point. Based on the titration curve, it is determined that K₂ = 9.5 x 10- 10 for the weak acid. Based on this information, what was the pH after only 39.28 mL of NaOH was added? Write your answer to 2 decimal places (ie. 1.23 or 12.34).
