Sulphur trioxide SO3 is an intermediate product during the manufacture of sulphuric acid contact process.

Sulphur dioxide is a colourless gas with a penetrating, choking odour. It dissolves readily in water to form an acidic solution sulphurous acid and is about 2.

In addition to the gas itself, if trees or other plants are exposed to wet or dry acid depositions from the emission source, they can also be harmed.

Agricultural crops, as well as freshwater lake and stream ecosystems are harmed by this deposition as it lowers the pH of water - this results in acidification. Exposure to sulfur oxides can be harmful to human health. Since sulfur oxides are irritants, they have been associated with reduced lung function, increased incidence of respiratory diseases, irritation of the eyes, nose, and throat, and even death. Acute exposures to higher concentrations are linked highly to negative health effects, but over time exposure to smaller amounts is just as harmful.

As well, since sulfur oxides are a component of acid rain , the emissions of sulfur oxide can affect building stone and other materials. Sulfurous acid is formed when sulfur dioxide reacts with moisture, and this acid accelerates the rusting process of a variety of metals. As well, acidic gases formed by SO x emissions can erode marble and limestone. The following data visualizations show the sources emitting SO x in Canada.

It is a colorless gas that smells like burnt matches. Sulfur trioxide is often a colorless or white solid that creates white fumes in the air and has strong reactions with water. Both sulfur dioxide and sulfur trioxide react to form sulfuric acid, which is toxic to living tissue and is the main component of acid rain.

When coal and oil burn, the sulfur in them combines with oxygen in the air to make sulfur oxides. Processing mineral ores that contain sulfur and industrial burning of fossil fuels are also sources of sulfur oxides in the atmosphere. Above are four different ways chemists represent sulfur trioxide.

Sulfur oxides pollute the air.
