Acid Rain and Its Effect on Limestone
Objective: Study the effects of acid rain on calcareous rocks like limestone.
Materials:
-
Vinegar (as a weak acid)
-
Tap water
-
2 identical pieces of limestone or chalk
-
2 jars
-
Labels
Procedure:
-
Place one piece of limestone in vinegar and the other in water.
-
Observe over several days, noting bubbling, disintegration, and changes in appearance.
Outcome:
Shows how acid rain (simulated by vinegar) erodes limestone, demonstrating real-world effects on buildings and natural formations.
