Pyridine (C5H5N) is a weak base (pkb = 8.74) with an unpleasant, sweet fishy odour. In a titration, 175.0mL of pyridine solution required 13.6 mL of 0.3250M  HCl to reach the equivalence point.

a) Calculate the pH of the solution at the equivalence point of the titration.

b) Sketch the shape of the pH curve you would obtain for this titration, and label all characteristic features of the graph.
