Challenge Problems

Push your limits with challenges.

Question 1

Given a weak base with Kb = 1.0 Γ— 10^-7 and an initial concentration of 0.1 M, calculate Ξ± and Kb.

πŸ’‘ Hint: Use simplifications based on the small value of Kb.

Question 2

In a scenario with a weak base dissolved at a concentration of 0.05 M in water, how would adding a common ion affect Kb?

πŸ’‘ Hint: Think about Le Chatelier's Principle when ions are added.
