Briefly state why trifluoroacetic acid is more acidic than acetic acid.
Explain why acid chlorides are more reactive than amides in reactions with nucleophiles.
Calculating the pH of a weak base titrated with a strong acid
An analytical chemist is titrating 101.7 mL of a 0.3500M solution of piperidine (C5H10NH) with a 0.05700M solution of HClO4. The pK of piperidine is 2.89.
Calculate the pH of the base solution after the chemist has added 682.9 mL of the HClO solution to it.
