Väävelhappega

Väävelhappega, often referred to as sulfuric acid in English, is a highly corrosive mineral acid. Its chemical formula is H2SO4. It is a colorless, odorless, and viscous liquid that is miscible with water. The reaction with water is highly exothermic, meaning it releases a significant amount of heat.

Väävelhappega is one of the most important industrial chemicals produced globally. Its primary uses include fertilizer manufacturing, particularly for phosphates, as well as in the refining of petroleum, processing of metals, and production of chemicals like detergents and dyes. It also finds applications in lead-acid batteries, as a dehydrating agent, and in chemical synthesis.

The production of väävelhappega typically involves the contact process, which includes the oxidation of sulfur dioxide to sulfur trioxide, followed by the absorption of sulfur trioxide into concentrated sulfuric acid. Due to its corrosive nature, väävelhappega must be handled with extreme care. Contact with skin can cause severe burns, and its fumes are irritating to the respiratory system. Proper protective equipment is essential when working with this chemical.
