Sulfuric acid - Wikipedia

OverviewChemical propertiesOccurrenceManufactureUsesSulfuric acid, also known as vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H2SO4. It is a colorless, odorless, and viscous liquid that is soluble in water and is synthesized in reactions that are highly exothermic. Its corrosiveness can be mainly ascribed to its strong acidic nature, and, if at a high concentration, its dehydrating and oxidizing properties. It is also hygroscopic, readily absorbing water vapor from the air. Upon contact,

Sulfite process - Wikipedia

The pulping liquor for most sulfite mills is made by burning sulfur with the correct amount of oxygen to give sulfur dioxide, which is then absorbed into water to give sulfurous acid. S + O 2 → SO 2 SO 2 + H 2 O ⇌ H 2 SO 3. Care must be taken to avoid the formation of sulfur trioxide since it gives undesired sulfuric acid when it is ...
