AP Environmental Science / Unit 7: Atmospheric Pollution
7.7 Acid Rain
Notes
$\mathrm{SO_2}$ and $NO_x$ react with water to form sulfuric and nitric acid.
- Effects: acidified lakes, damaged forests, leached soil nutrients, corroded buildings.
- Limestone (calcium carbonate) can neutralize it.
Practice
Acid rain forms mostly from:
Strong acids.
Lakes on limestone bedrock resist acid rain because:
Buffering.
Acid rain harms forests by:
Nutrients wash out.
