For each of the following three questions 25.0 mL of 0.100 Mpyridine (Kb = 1.70 x 10-9) istitrated with 0.100 M HCl. For each question calculate the pH ofthe final solution after the indicated amount of HCl has been added. That is, treat each question as a separate titration.
Pyridine is monobasic, i.e., each molecule of pyridine accepts onlyone proton from a molecule of acid. Remember that the final volume of the solution is the sum of the initial volume and the volume ofHCl that is added to it.
