How Can Acid Rain Be Produced?

Acid rain is caused by air pollution.The nitrogen and Sulphur compound in the polluted air mix with the water vapour to produce nitric acid and sulphuric acid respectively.Acid rain is highly corrosive due to its acidic nature.it is harmful to living organism both in land and in water.

Oxides of sulphur and nitrogen are important pollutants of air . When they dissolve in water of atmosphere they get oxidised in acids and fall on ground as ACID RAINS .Acid rains is a mixture of  H2SO4 and HNO3 in water .
         Acid rains increases soil acidity affecting soil flora and fauna cause acidification of lakes and streams affecting aquatic life ,production of crop ,and human health . Acid rains also corrode buildings ,monuments ,bridges ,statues etc Due to acidity , levels of heavy metals such as aluminium ,manganese ,zinc ,cadmium ,lead ,copper ,increases in soil and water beyond safe limit .This kills many bacteria ,blue green algae ,fishes etc disrupting ecological balance .
