Väävelhappeid

Väävelhappeid is the Estonian term for sulfuric acid compounds. Sulfuric acid, with the chemical formula H2SO4, is a highly corrosive and strong mineral acid. It is a colorless, odorless, and viscous liquid that is soluble in water. In its concentrated form, it acts as a dehydrating agent, meaning it can remove water molecules from other substances. This property makes it useful in various industrial processes.

Sulfuric acid is one of the most important industrial chemicals globally. Its production and use are indicators of a nation's industrial strength. It plays a critical role in the manufacturing of fertilizers, particularly phosphates. It is also used in the refining of petroleum, the production of chemicals such as hydrochloric acid and nitric acid, the processing of metal ores, and the manufacturing of dyes, explosives, and pharmaceuticals. In laboratories, it is commonly used as a catalyst and a dehydrating agent.

The production of sulfuric acid typically involves the contact process. This process involves burning sulfur or sulfur-containing ores to produce sulfur dioxide, which is then oxidized to sulfur trioxide. The sulfur trioxide is subsequently reacted with water to form sulfuric acid. Due to its corrosive nature, handling sulfuric acid requires strict safety precautions, including the use of protective clothing and ventilation.
