ACID RAIN

Carbon Dioxide, Sulfur Dioxide, Hydrogen Chloride all create an acidic solution.


Carbonic Acid - Dissolved Carbon Dioxide


Sulfur Dioxide - "acid rain" - kill forrest, pollute water (river, lake, pond)

(Found in volcanoes and industrial pollution)

Limestone/Sinkholes

Limestone: porpous (holds water), soluble in water (carbonic acid), soft


FLORIDA SINKHOLES HAPPEN BECAUSE: lots of limestone, water underground (aquafor), once covered with ocean (soft calcium deposits 'dead animals')


Sulfuric Acid

Discovered in 8th century by alchemist: alchemy "chemistry"


Alchemist- try to make gold out of everything


USES:

Lead Acid batteries (cars)

Fertilizers

Steel industry (prevents rust corrosion)

Dried fruit production (hydrotropic)
