Challenge Problems
Push your limits with challenges.
Question 1
You have three solutions: one acidic, one basic, and one neutral. You only have litmus paper and phenolphthalein as indicators. Describe how you would test each solution and what results you would expect.
💡 Hint: Think about the color changes each indicator indicates.
Question 2
