Calculating the pH of a weak base titrated with a strong acid
An analytical chemist is titrating 184.2 mL of a 0.7800M solution of dimethylamine ((CH3)
NH with a 0.3000M solution of HClO4. The pK₁ of
dimethylamine is 3.27. Calculate the pH of the base solution after the chemist has added 424.1 mL of the HClO solution to it.
