Problem- The pKb values for bibasic base B are pKb1= 2.10 and pkB2= 7.39, calculate the pH at the flowing points in titration of 50.0mL of a .55M B with .55M HCl.
1) Before any addition of HCl
2) After adding 25mL HCl
3) After adding 50mL HCl
4) After adding 75mL HCl
5) After adding 100mL HCl
I want you to clarify the chemistry in this above problem.
