Introduction: The components
that make up acid rain are produced through many everyday process,
but mainly as a byproduct of the gasoline engine and electrical generation.
In power generation coal is burned and the excess waste is put out
the smoke stack. One of these byproducts is elemental sulfur. As sulfur
is burned with the coal it combines with oxygen in the air to form
sulfur di- and tri-oxide. This is a simple composition reaction: Now we have a problem, acid in the atmosphere. Now sulfur has formed an acid that will be carried in the cloud until the next rain storm. Unfortunately for the area under the storm the acid will fall from the sky gather in the rivers and collect in the reservoirs. This collection of acid rain leads to many environmental and economic problems.
