Challenge Problems
Push your limits with challenges.
Question 1
You have a solution of 0.3 M carbonic acid (H2CO3). Calculate the pH considering both dissociation constants Ka1 and Ka2 if necessary.
💡 Hint: Focus on the first dissociation; the second can often be neglected.
Question 2
Suppose you need to neutralize a 0.1 M acetic acid solution. How much NaOH would you need to reach pH 7?
💡 Hint: Neutralization occurs in equal molar ratios.
