Acid rain is known to contain some acids.Name these acids and where from they come in rain ?

Answer»

Solution :Acid rain contains `H_2 CO_3, HNO_3 and H_2 SO_4` . `H_2 CO_3` is formed by the dissolution of `CO_2` of the air in which the water vapour present.
`CO_2 + H_2 O to H_2 CO_3`
Forest fire and lightning are the natural are the natural source of NITRIC oxide (NO) . Nitrogen oxides are also produced by combustion engines , aircraft , furnaces , incinerators , industrial PLANTS .
Nitric oxide slowly reacts with atmospheric AIRAND produce `NO_2 . NO_2` dissolves in water to form `HNO_3`.
`3NO_2 + H_2 O hArr 2HNO_3 + NO`
SULPHUR oxides are produced by the burning of fossil fuels and in extraction of metals from their sulphide ORES etc. Sulphur dioxide also produces sulphuric acid in the similar way.
`SO_2+ O_2 + H_2 O underset("Metal oxide")overset("Soot particles")to H_2 SO_4 + [O]`
