Challenge Problems
Push your limits with challenges.
Question 1
A diprotic acid H₂A has Ka₁ = 1.0 × 10⁻⁴ and Ka₂ = 5.0 × 10⁻¹². Calculate the pH at the first and second equivalence points during titration with NaOH.
💡 Hint: Use the average of the pKa values for the first and identify the pKb for the second.
Question 2
During the titration of 0.1 M of a diprotic acid H₂X with NaOH, after adding 50 mL of titrant, the pH was measured to be 8.5. If the volume of solution was 200 mL, what can be inferred about the average concentration of conjugate base formed?
💡 Hint: Focus on the stoichiometric ratios when calculating the concentration of the conjugate base.
