Question:

A species that can accept two protons is classified as dibasic.
The dibasic molecule 1,2-ethanediamine, H₂NC₂H₄NH₂, which has pK_b1 = 3.19 and pK_b2 = 6.44, is titrated with HCl(aq).

(a) What is the pH when [H₂NC₂H₄NH₂] = [H₂NC₂H₄NH₃⁺]?

(b) What is the pH when [H₂NC₂H₄NH₃⁺] = [⁺H₃NC₂H₄NH₃⁺]?
