Borate anions are largely in the form of the undissociated acid in aqueous solution at physiological pH. No further metabolism occurs in either animals or plants. In animals, boric acid/borate salts are essentially completely absorbed following oral ingestion. Absorption occurs via inhalation, although quantitative data are unavailable.
Boranes are chemical compounds of boron and hydrogen, with the generic formula of B x H y. These compounds do not occur in nature. Many of the boranes readily oxidise on contact with air, some violently. The parent member BH 3 is called borane, but it is known only in the gaseous state, and dimerises to form diborane, B 2 H 6. The larger ...
Takedaite is a borate with the presence of calcium, boron and oxygen. Chemical analysis gave CaO 71.13%, B 2 O 3 28.41%, the H 2 O content was determined by ignition loss at 900°C and was 0.14%, totaling 99.68%. The empirical formula calculated on the basis of O=6 is therefore Ca 3.053 B 1.965 O 6 or more ideally Ca 3 B 2 O 6. [4]
Zinc borate refers to a family of inorganic compounds consisting of borate of zinc.They are white solids with the formulas 4ZnO·B 2 O 3 ·H 2 O, ZnO·B 2 O 3 ·1.12H 2 O, ZnO·B 2 O 3 ·∼2H 2 O, 6ZnO·5B 2 O 3 ·3H 2 O, 2ZnO·3B 2 O 3 ·7H 2 O, 2ZnO·3B 2 O 3 ·3H 2 O, 3ZnO·5B 2 O 3 ·14H 2 O, and ZnO·5B 2 O 3 ·4.5H 2 O.
Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula B(OH) 3. It may also be called hydrogen orthoborate, trihydroxidoboron or boracic acid. [3] It is usually encountered as colorless crystals or a white powder, that dissolves in water, and occurs in nature as the mineral sassolite.
The hydrated tetraborate anion occurs in the mineral borax (sodium tetraborate octahydrate) with the formula Na 2 [B 4 O 5 (OH) 4]·8H 2 O. The borax chemical formula is also commonly written in a more compact notation as Na 2 B 4 O 7 ·10H 2 O. Sodium borate can be obtained in high purity and so can be used to make a standard solution in ...
Sodium borate is a generic name for any salt of sodium with an anion consisting of boron and oxygen, and possibly hydrogen, or any hydrate thereof. It can be seen as a hydrated sodium salt of the appropriate boroxy acid , although the latter may not be a stable compound.
The Borate Minerals are minerals which contain a borate anion group. The borate (BO 3) units may be polymerised similar to the SiO 4 unit of the silicate mineral class. This results in B 2 O 5, B 3 O 6, B 2 O 4 anions as well as more complex structures which include hydroxide or halogen anions. [2] The [B(O,OH) 4] − anion exists as well.
