A chemist titrates 180.0 ml. of a 0.8115M cyanic acid (HCNO) solution with 0.7971 M NAOH solution at 25 "C. Calculate the pH at equivalence. The pk, of cyanic acid is 3.46. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the intial volume plus the volume of NaOH solubion added. ?
