1. ACID DEPOSTION a.k.a. Acid rain

2. What is acid deposition?
pH less than 7
Wet
Rain
Snow

4. COLA

5. What happens when you mix pH?
Acid + Base= neutral
Add bases (antacid) to acids to neutralize!
BASES ARE GOOD FOR ACID RAIN NEUTRALIZATION!!!

8. Acid rain in Europe

9. ACID RAIN IS MANY ACIDS
Sulfuric acid
Nitric acid
Carbonic acid

10. Sulfuric acid
Source
Coal burning power plants (electricity)
industry

11. Nox
Sources-
Gasoline burning
industry

12. Carbonic acid Natural From volcanoes, respiration
Burning of fossil fuels
Acid used in most cave formation
Limestone + carbonic acid = calcium bicarbonate (soluable)

14. EFFECTS OF ACID RAIN

15. Wears away rock and metal

16. Harms aquatic life

17. KILLS PLANTS
Especially conifers
Black Forest (Germany)

18. Does acid rain hurt people?
Indirectly
Breath in harmful particulates that damage lung tissue

19. SOLUTIONS?
Smokestack scrubbers on coal burning plants

20. Solutions
Wash coal (less sulfur)

21. Solutions
Catalytic converters on cars
(filter Nox)

22. Solutions
Alternative energy sources (less fossil fuels)
