Metaborinsäure

Metaborinsäure, also known as boric acid, is a chemical compound with the formula H3BO3. It is a white crystalline solid that is soluble in water and has a slightly sweet taste. Boric acid is a weak acid and is commonly used as a mild antiseptic, insecticide, and flame retardant. It is also used in the manufacture of borax, borax glass, and other borate compounds.

The primary source of boric acid is the mineral borax, which is mined and then processed to produce boric acid. Boric acid can also be synthesized through the reaction of borax with sulfuric acid. It is typically found in its anhydrous form, but it can also exist in a hydrated form, such as boric acid monohydrate (H3BO3·H2O).

Boric acid has a variety of applications in different industries. In the medical field, it is used as an antiseptic to treat minor cuts and burns. It is also used as a preservative in some cosmetics and personal care products. In the agricultural sector, boric acid is used as an insecticide to control pests in crops. Additionally, it is used in the manufacturing of glass and ceramics, as well as in the production of flame retardants for textiles and plastics.

Despite its usefulness, boric acid can be toxic if ingested in large amounts. It can cause gastrointestinal irritation and, in severe cases, can lead to metabolic acidosis. Therefore, it is important to handle boric acid with care and follow proper safety guidelines when using it.
