How Does Acid Rain Form Bbc Bitesize

These gases when released into the atmosphere react with the water oxygen and other gases and chemicals present to form various acidic compounds sulphuric acid and nitric acid.

How does acid rain form bbc bitesize. Natural rain is slightly acidic due to dissolved carbon dioxide. If sulfur dioxide gets into the atmosphere it reacts with water and oxygen in the air to form a dilute solution of sulfuric acid. One of the causes of acid rain is volcanic eruptions but its main cause is the release of sulphur dioxide and nitrogen oxide during fossil fuel combustion. Acid rain occurs when sulfur dioxide and nitrogen oxides are released into the air where they rise and mix with water oxygen and other chemicals.

When the gas sulfur dioxide dissolves in water an acidic solution is formed. What is acid rain. Sulphur dioxide and the oxides of nitrogen will mix with rainwater in clouds and form acidic solutions. These substances can rise very high up into the atmosphere where they mix and react with water oxygen and other chemicals to form more acidic pollutants called acid rain.

Fossil fuels naturally contain sulfur compounds. The acid rain will kill trees and damage buildings made from limestone. When sulfur dioxide dissolves in water droplets in clouds. These then fall as acid rain.

These produce sulfur dioxide a gas with a sharp choking smell when the fuel is burned. Sulfur dioxide and nitrogen oxide readily dissolve in water and can be carried several miles by the wind. The effects acid rain has severe effects on the environment and individual ecosystems within it. Sulfur dioxide and nitrogen oxides dissolve very easily in water and can travel great distances to combine with the moisture in the air.

Sulfur dioxide is produced when fossil fuels containing sulfur impurities are burned. Clouds are made from water so this. Acid rain is a product of the chemical reaction of sulfur dioxide and nitrogen oxide that is released with water oxygen and other chemicals into the atmosphere. Natural rain has a ph of 5 5 acid rain has a ph of 4.
