For each of the following three questions 25.0 mL of 0.100 M pyridine (Kb = 1.70 x 10-9) is titrated with 0.100 M HCl. For each question calculate the pH of the 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 only one proton from a molecule of acid. Remember that the final volume of the solution is the sum of the initial volume and the volume of HCl that is added to it.Calculate the pH after the addition of 16.0 mL of 0.100 M HCl
