Seriously, 4.9 - Acidification Lab
Acid Rain
Carbon Dioxide + Sulfur Dioxide = An acidic solution (AKA Acid Rain)
Causes of Acid Rain:
-Volcanos
-Industrial Pollution
-Burning of gas (cars)
Results:
-Kills forests
-Pollutes water (Rivers, Lakes, Ponds)
Carbon Dioxide + Sulfur Dioxide = An acidic solution
Sinkholes
-Porous
-Soft of Moe's Scale
-Soluble in Water
Florida Sinkholes occur because:
-Lots of Limestone
-Water Underground
-Florida was once under an Ocean
Sulfuric Acid
Alchemists:
-Medieval Scientists bent on making gold from cheaper materials
Uses:
-Lead acid batteries
-fertilizers
-Steel industry (it prevents corrosion)
-Dried fruit (hydrotropic)
The Sulfuric Acid Lab
-flame test showed that the reaction was green
Phenol Red
The purpose of the lab:
To see if we can change the acidity of the water by dissolving carbon dioxide from our lungs.
Result:
Absolutely
Calcium Tablet:
Result: The tablet in the cup that was blown on did not retain its shape, and it started to dissolve in the water. The non blown on tablet in cup only lost a little material, and it retained its shape.
Ph level in Ocean is rising
- 8.1 - 8.4
-the level has lowered about 0.1 (-25%)
