Acid Rain Eats Stone!

Add to list Go to activity
This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies. One bunny gets doused with sulfuric acid, and the other bunny is covered in water. Learners can watch the effects of both liquids on the stone with a magnifying glass. The chalk contains calcium carbonate (CaCO3), and the acid reacts to form carbon dioxide (CO2) bubbles. For safety reasons, this activity works best as a demonstration for younger audiences.
