Add each ingredient and watch the water change.
The water is clean and safe. pH is neutral.
It is not just "dirty water." The danger is low pH + dissolved metals.
Clue 3 / 3 · The Solution
Which cup actually changes the chemistry?
Acid water → filter → chalk. Which step truly fixes it?
✓ Correct
③ Chalk treatment
Chalk (calcium carbonate, CaCO₃) is a base. It neutralizes the acid and raises the pH — so it truly changes the chemistry. A filter only removes solids. In real life this treatment must run continuously, because the rock keeps making acid underground.
