Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What does Kb represent?
💡 Hint: Think of what happens when a base dissolves in water.
Question 2
Easy
Which base has a higher strength: one with Kb = 2.0 or Kb = 0.0002?
💡 Hint: Recall that higher Kb indicates greater dissociation.

Challenge Problems
Push your limits with challenges.
Question 1
Calculate the Kb for a weak base if you find 3% of it dissociates in a 0.2 M solution.
💡 Hint: Start by determining the [OH-] from the percentage dissociated.
Question 2
If a base has Kb = 9.0 × 10⁻⁶, what is Ka for its conjugate acid?
💡 Hint: Use the Kw value at 25 °C to find Ka.
