An analytical chemist is titrating 179.6 mL of a 0.8400M solution of cyanic acid (HCNO) with a 1.200M solution of KOH. The p K, of cyanic acid is 3.46. Calculate the pH of the acid solution after the chemist has added 144.3 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. 0 pH =

A chemist titrates 150.0 mL of a 0.0676M dimethylamine ((CH,) NH) solution with 0.4402M HBr solution at 25 °C. Calculate the pH at equivalence. The pK, of dimethylamine is 3.27. 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 HBr solution added. pH = Explanation Check 2021 McGraw-Hill Education.
