Resumen
Acid rain is a phenomena associated to high
production, depending mainly of fossilized fuel
consuming and of certain agro cultural practices as
burnings, which release several substances like
sulphur and nitrogen oxides to the atmosphere,
aporting the raw material to make up the sulphuric
and nitric acids which later return to the hearth surface
as liquids as sprays and affect the natural
ecosystems.
Rain water is slightly acid because it contains
carbonic acid, formed from the atmospheric carbonic
dioxide. Rain, which usually has a pH of approximately
5.6, can reach a measure close to 7.0, due to the
presence of other alkaline substances in the
atmosphere, and those substances neutralize the
carbonic acid.
