Question- The pKb values for the dibasic base B are pKb1 = 2.10 and pKb2 = 7.50. Calculate the pH at each of the following points in the titration of 50.0 mL of a 0.50 M B(aq) with 0.50 M HCl(aq).
1) Before addition of any HCl
2) After addition of 25.0mL of HCl
3) After addition of 50.0mL of HCl
4) After addition of 75.0mL of HCl
5) After addition of 100.0mL of HCl
