Year 11 MYP Project: Acids: Acid Rain
What are the chemical causes of acid rain? How is acid rain formed? ... Does Bangkok suffer from acid rain? ...
Acid rain is water vapor, which reacts with airborne acids and then falls to the surface of earth. The primary causes of acid rain are acidic oxides , precisely sulfur dioxide (SO2) and nitrous oxide (NOx- since this can be nitrogen dioxide (NO2) or nitric oxide (NO)) and some carbon dioxide (CO2). Acid rain occurs when these gases react in the atmosphere with water, oxygen, and other chemicals to form various acidic compounds. The result is a mild solution of sulfurous acid, nitric acid, and carbonic acid which then falls onto earth. ...
Sulfur dioxide (SO2)
Sulfur trioxide (SO3) Heat and power generation facilities that use oil or coal containing sulfur- coal contains 2-3% sulfur; sulfuric acid plants, combustion, industries which process raw ore containing sulfides in order to obtain copper, zinc, or nickel also cause an increase in sulfur dioxide levels in the atmosphere.
Nitrogen dioxide (NO2)
Motor-vehicle exhaust contains 50% of nitrogen dioxide; heat and power generation; nitric acid; explosives; fertilizer plants, combustion
How does acid rain form. ...
SO2 + H2O --> H2SO3 or sulfur dioxide + water --> sulfurous acid
SO3 + H2O --> H2SO4 or sulfur trioxide + water --> sulfuric acid
CO2 + H2O --> H2CO3 or carbon dioxide + water --> carbonic acid
4NO2 + 2H2O + O2 --> 4HNO3 or nitrogen dioxide + water + oxygen --> nitric acid
After the mild solution of acid is formed, they precipitate and fall on earth. ...
The basic brief steps of how acid rain forms is as follows:
1. ... Pollutants may be carried in clouds for long distances before falling, which means that forests and lakes far away from factories may be damaged by acid rain. ... Some particles do not mix with water and reaction and thus these fall on to the earth as dry rain. ...
Why are people so worried about acid rain? ... Well, acid rain causes many, many problems.
