brennisteinssýru

Brennisteinssýra is the Icelandic word for sulfuric acid. Sulfuric acid is a highly corrosive strong mineral acid with the molecular formula H2SO4. It is a colorless, odorless, and viscous liquid that is miscible with water. In industry, it is produced on a massive scale and is one of the most important chemicals manufactured globally. Its primary uses include fertilizer manufacturing, in mineral processing, oil refining, wastewater processing, and in chemical synthesis.

The production of sulfuric acid is a key indicator of a nation's industrial strength. The contact process is the most common method for its manufacture. This involves the oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3), typically using a vanadium pentoxide catalyst, followed by the reaction of sulfur trioxide with water to form sulfuric acid.

Sulfuric acid reacts exothermically with water, meaning it releases heat. It is also a powerful oxidizing agent and dehydrating agent. Due to its corrosive nature, careful handling and appropriate safety precautions are essential when working with this chemical. Personal protective equipment, such as gloves, eye protection, and protective clothing, is necessary. Storage should be in suitable containers made of resistant materials.
