Challenge Problems
Push your limits with challenges.
Question 1
You perform a titration of 50 mL of a weak acid with a known concentration of 0.1 M with a strong base. Given that the pKa of the weak acid is 4.76, which indicator would you use and why?
💡 Hint: Consider where the equivalence point will lie based on the nature of the acid.
Question 2
For a certain titration, you find that the equivalence point occurs when 25 mL of a strong acid has been added to 50 mL of a weak base. Calculate the resulting pH at the equivalence point, considering the weak base's pKb.
💡 Hint: Use the relationship between pKa and pKb to solve!
