Sulfuric acid

From Glossary of Meteorology

sulfuric acid

Strong acid, formula H2SO4, formed as the end product in the oxidation of most sulfur compounds.

Sulfuric acid is a major constituent of acid rain associated with fossil fuel combustion. As a consequence of its low volatility, it can lead to particle formation, and is a major constituent of cloud condensation nuclei and the background aerosol, including the stratospheric sulfate layer.
