A chemist titrates 50.0 mL of a 0.4918M hydrocyanic acid (HCN) solution with 0.8729M KOH Solution at 25 °c. Calculate the pH at equivalence. The pk of hydrocyanic acid is 9.21. 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 KOH solution added. pH = 0 X
