- Rain or precipitation with a pH lower than 5.6

- Normal rain water has a pH lower than 7

- Carbon dioxide dissolves in water to form carbonic acid

-Carbonic acid ionizes

water to form hydronium ions

Oh NO!

-Electricity generation, factories and motor vehicles

-Burning of fuels

-High temperature causes sulphur to react with oxygen to produce sulphur dioxide

-High temperature causes nitrogen to react with oxygen to produce nitrogen dioxide.

- Gases dissolve in water to produce acids

-Volcanic eruption that emits acid-producing gases like sulphur dioxide.

-Dimethyl sulphide oxidized by phytoplanktons in oceans to produce sulphur dioxide

-Sulphur dioxide dissolves in water to form sulphuric acid

- wildfires

• Affect the soil

-some of the organism do not adapt to such a acidic habitat

- the acid rain makes some forests have been growing more and more slowly

• The aquatic animals

- some aquatic organism cannot bear the acidity of the water caused by the acid rain and this greatly affects their living.

-Sulphuric acid in polluted precipitation interferes with the fish's proficiency to take in oxygen, salt, and nutrients

• The rock and man-made materials

-acid rain also damages man-made materials and structures

- toxic gases may even be released and this posts a threat to our human’s health

• About the sulphur dioxide

-use low sulphur-content coal

• -Use Scrubbers ~ The sulphur dioxide gas reacts with the lime to produce a solid of calcium sulphate.

Photos of scrubber

• About the nitrogen oxides

- installation of catalytic converters ~This converts nitrogen oxides, carbon dioxides and unburned hydrocarbons into a cleaner state to reduce the oxides of nitrogen.
