Acid Rain
What are the chemical causes of Acid Rain?
How is Acid Rain formed? ...
Does Bangkok suffer from Acid Rain? ...
“Acid Rain” is commonly defined as the natural process of laying down a deposit of acid components or “acid deposition” in snow, fog, dew and dry particles. A more accurate term used to describe acid rain is “Acid precipitation”. We can know if the rain in acidic, it has a Ph of less than 5. ... 6 is considered to be significantly neutral for rain acid measurements.
There are many factors that contribute to the formation of acid in rain and the main cause of it is smoke and gases that are given off by factories and cars that run on fuel oils or commonly termed as fossil fuels. ... Once in the atmosphere, sulfur dioxide and nitrogen oxides undergo complex chemical reactions with water vapor and other chemicals to form sulfuric acid, nitric acid, and other pollutants called nitrates and sulfates. The acid compounds are carried by air currents and the wind. When clouds fog form in acid-laden air, they too are acidic, and so rain or snow that falls from them is obviously acidic too. These chemical compounds are the reason and cause of acid rain.
Some of these complex reactions are
SO2 (gas derived from burning of fossil fuels) + O2 (moisture in the atmosphere) - > SO3 (g)
In later stages, the Sulphur Trioxide changes into Sulphuric Acid when it reacts with atmospheric water vapour to form Sulphuric acid.
SO3 (g) + H2O (l) - > H2SO4 (aq)
Acid rain is very harmful as the acid in it is extremely corrosive and it “eats” everything it meets.
