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)
