Acid Rain and Global Warming
Gasses dissolved in our atmosphere:
- CO2 (creates an acidic solution)
- Sulfur Dioxide (creates an acidic solution)
- Hydrogen Chloride (creates an acidic solution)
Sulfur dioxide= "acid rain" (bad for environment)
-volcanoes

Box Questions
32. Denver (at the base of the Rocky Mountains)
33. 0.05 g/cm3 18.25 g/cm3
34. Almost all water contains toxic substances
35. Deserts were once an ocean, no rain to wash away/ dissolve solids at surface
Limestone/ Sinkholes
Limestone= porous (holds H20), soft, soluble in H20 (carbonic acid)
Florida Sinkholes occur bc...
- lots of limestone
- water underground (aquifer)
- once covered with ocean= soft calcium deposits (dead animals)
Sulfuric Acid Notes
Discovered in 8th century by Alchemist= Alchemy ("chemistry")
-Alchemists wanted to make gold out of rocks
Uses:
-Lead Acid batteries
-Fertilizers
- Steel industry= prevents rust corrosion
-dried fruit production (hydrotropic)
Ocean Acidification
Normal Ocean pH is 8.1-8.4
- Ocean's pH decreased 0.1 (about 25%)
- lower pH means sea animals won't be able to make shells (ex...crabs, shrimp, clams...)
