4.9-Acidification Lab Quiz
Acid Rain
Gases dissolved in our atmosphere:
CO2, Sulfur Dioxide, and Hydrogen Chloride create an acidic solution
Carbon acid --> Dissolved CO2
Sulfur dioxide --> "acid rain" = Kill forest, pollute water (rivers, lakes, pond)
- Volcanoes and industrial pollution
Limestone and Sinkholes
Limestone: porous (holds water), soft, and soluble in water (carbonic acid)
Florida sinkholes occur because:
Lots of limestone
Water underground (aquifer)
Once covered with ocean --> soft calcium deposits (deep animals)
Labs: Two Gases and Acidification
Sulfuric Acid
Discovered in 8th century by Alchemist --> Alchemy --> Chemistry
Uses:
Lead Acid batteries (cars)
Fertilizers
Steel industry --> prevents rust corrosion
Dried fruit production (hydrotropic)
Ocean Acidification
Normal ocean ph is 8.1-8.4
Ocean's oh has decreased 0.1 (about 25%)
Lower ocean ph means sea animals with shells with not be able to make a shell (clams, shrimp, clams, etc.)
