Challenge Problems
Push your limits with challenges.
Question 1
A solution has a pH of 11. What is the concentration of hydroxide ions, and what is its pOH?
💡 Hint: Start by finding the pOH and then use that to find hydroxide concentration.
Question 2
If a solution with pOH changes to 9 due to dilution, what was the original pH?
💡 Hint: Use the relationship pOH + pH = 14 to find the initial pH.
