The pH of a 0.3M pyridine (C5H5N) solution is 9.38. To this solution you add 0.15M Pyridinium Chloride (C5H6NCl).
a) Do you expect the pH of the new solution to be greater, less than or equal to the original Pyridine solution? Why? (BRIEFLY explain your reasoning)
b) Calculate the new pH of the solution. Pyridine is a weak base with Kb=2.0x10^-9
