The pKb values for the dibasic base B are pKb1 = 2.1 and pKb2 =7.5. Calculate the pH at each of the following points in thetitration of 50.0 mL of a 0.95 M B(aq) with 0.95 MHCl(aq).

(a) before addition of any HCl (b) after addition of 25.0 mL of HCl(c) after addition of 50.0 mL of HCl (d) after addition of 75.0 mLof HCl (e) after addition of 100.0 mL of HCl

Answer rating: 100% (QA)
