Calculating the pH of a weak acid titrated with a strong base An analytical chemist is titrating 199.4 mL of a 1.200M solution of cyanic acid (HCNO) with a 0.7400M solution of KOH. The pK of cyanic acid is 3.46. Calculate the pH of the acid solution after the chemist has added 362.5 mL of the KOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of KOH solution added. Round your answer to 2 decimal places. pH = 0 G Izabella 000
