Textbook Question
Chapter 20.15, Problem 20.22P
Propose a mechanism for the reaction of benzoic acid with oxalyl chloride. This mechanism begins like the thionyl chloride reaction, to give a reactive mixed anhydride. Nucleophilic acyl substitution by chloride ion gives a tetrahedral intermediate that eliminates a leaving group, which then fragments into carbon dioxide, carbon monoxide, and chloride ion.

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.
4
Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HClO solution added.
