4.9 - acidification lab
My Guide
Gas dissolves in our atmosphere
Acidic solution: CO2, Sulfuric dioxide, Hydrogen Chloride
Carbonic acid contains dissolved CO2
Sulfuric dioxide is "acid rain" and from volcanoes and industrial plants
Acid rain:
- kills forests
- pollutes waters
Limestone:
- porous
- soft
- soluble in water
Florida sinkholes happen because:
- lots of limestone
- water underground (aquifer)
- Used to be covered by ocean (soft calcium deposits)
When and by who was sulfuric acid found by?
- 8th century
- Alchemist
Uses for sulfuric acid:
- Lead acid batteries (cars)
- fertilizers
- Steel industries: prevents rust corrosion
- dried fruit production (hydrotropic)
Magnesium carbonate and acid:
- more dense than the air
- sinks (CO2)
Magnesium and Acid:
- lighter than air (less dense)
- floats (hydrogen)
