Pyridine, C₅H₅N, is probably better know as a Lews base, but it also acts as a Bronsted-Lowry base in water by increasing the concentration of hydroxide ion.

1. Write a chemical equation showing C₅H₅N acting as a base in water.

A 40 mL solution of 0.20M C₅H₅N(aq) was titrated with 0.20M HCl(aq)

A. Write a chemical equation showing the titration reaction.

B. Calculate the pH after 30mL of 0.2M HCl(aq) is addㄷd. Assume two significant figures in all calculations

C. Calculate the pH after an additional 30mL (60mL total) of 0.2M HCl(aq) is added.
