ACID RAIN

.Gases dissolve in atmosphere

.Carbon Dioxide, Sulfur Dioxide, Hydrogen Chloride all create acidic solutions

.Carbonic Acid= CO2

.Sulfur Dioxide= Acid Rain

.Sulfur Dioxide is in volcanos and is a cause of industrial pollution.

.Acid rain can kill forests, pollute water

LIMESTONE AND SINKHOLES

.Limestone is porous, soft and is soluble in water with carbonic acid)

.Sinkholes in Florida occur because of:

-Underground aquifers

-Florida was once covered with ocean--> soft calcium deposits and dead animal shells make up limestone

.Desert have large amounts of acid rain because they were once oceans which means the chemicals that were dissolved in the water dissolve into the deserts and because of the lack of rain the chemicals never wash away

SULFURIC ACID

.Discovered 8th century by alchemists

-Alchemy was a type of chemistry

USES

.Lead acid batteries

.Fertilizers

.Steel industry --> prevents rust corrosion

.Dried fruit production (hydrotropic)


Hydrotropic: Attracts water
