Beacuse the SO2 reacts with rain water to produce sulfurous acid.

SO2 + H2O ----> H2SO3 and this can be further oxidized to sulfuric acid.

Why do governments monitor emissions of sulfur dioxide and nitrogen oxides?

Because they are major pollutants that contribute to acid rain.


Why do oil companies advertise that their fuels are low in sulfur?

high sulfur fuel results in sulfur dioxide emissions which contribute to ground level pollution, acid rain and respiratory illness. In effect the companies are saying that their fuels do not have this problem as much as others.

What are the positive effects of acid rain?

Well the concentration of sulfur in acid rain cuts back the emissions of the greenhouse gas methane, but that's it.


Why do you need to cut down on sulfur emissions?

Sulphur dioxide is between the causes of acid rains, influence the corrosion of metallic structures, is a component of the air pollution in towns, is a problem for the health of men and animals, contribute to the global warming

What is the important cause of acid rain?

Pollution. More specifically, "Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids."


What is acid in acid rain?

Acid rain refers to any form of precipitation that contains higher than normal levels of hydrogen ions (giving it a low pH, and thus, making it more acidic). Acid rain is generally caused by sulfur dioxide (SO2) and nitrogen oxide (NOx) emissions; these emissions can either be from natural sources (e.g. Volcanoes) or human-related ones (e.g. factory combustion). Therefore, the acid in acid rain is either sulfuric acid, or nitric acid.
