Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A 0.1 M acetic acid solution is titrated with NaOH. Calculate the pH at the equivalence point.

💡 Hint: Remember that pH will be affected by the weak base generated from the weak acid.

Challenge 2 Hard

Given the Ka of an unknown acid is 4.0 × 10⁻⁷, determine if its conjugate base is strong or weak.

💡 Hint: Remember, a high Ka will indicate a low Kb.
