Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the difference between a weak acid and a strong acid?
💡 Hint: Think about what happens when each is mixed with water.
Question 2
Easy
Given a weak acid with Ka = 1.0 x 10⁻⁷ and C₀ = 0.1 M, find x.
💡 Hint: Use the approximation for weak acids.

Challenge Problems
Push your limits with challenges.
Question 1
Given a 0.15 M formic acid solution with a Ka of 1.8 x 10⁻⁴, calculate the pH.
💡 Hint: Bear in mind the approximation principles we've discussed.
Question 2
If we have a weak base solution of sodium bicarbonate at 0.1 M, find the pH knowing Kb is 2.3 x 10⁻⁸.
💡 Hint: Remember to apply Kb for weak bases similarly to Ka for weak acids.
