A borate is any of a range of boron oxyanions, anions containing boron and oxygen, such as orthoborate BO 3− 3, metaborate BO − 2, or tetraborate B 4 O 2− 7; or any salt of such anions, such as sodium metaborate, Na + [BO 2] − and borax (Na +) 2 [B 4 O 7] 2−. The name also refers to esters of such anions, such as trimethyl borate B ...
Borax (also referred to as sodium borate, tincal (/ ˈ t ɪ ŋ k əl /) and tincar (/ ˈ t ɪ ŋ k ər /)) is a salt (ionic compound), a hydrated or anhydrous borate of sodium, with the chemical formula Na 2 H 20 B 4 O 17. [1] [a] It is a colorless crystalline solid that dissolves in water to make a basic solution.
Boric acid predominates in solution below pH 9 Boric acid buffers against rising pH in swimming pools. Boric acid in equilibrium with its conjugate base the borate ion is widely used (in the concentration range 50–100 ppm boron equivalents) as a primary or adjunct pH buffer system in swimming pools.
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 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 ...
In organic chemistry, borate esters are organoboron compounds which are conveniently prepared by the stoichiometric condensation reaction of boric acid with alcohols. There are two main classes of borate esters : orthoborates , B(OR) 3 and metaborates , B 3 O 3 (OR) 3 .
Trisodium borate is a chemical compound of sodium, boron, and oxygen, with formula Na 3 BO 3, or (Na +) 3 [BO 3] 3−. [3] It is a sodium salt of the orthoboric acid B(OH) 3 . The compound is also called trisodium orthoborate , sodium orthoborate , or just sodium borate .
Disodium octaborate is a borate of sodium, a chemical compound of sodium, boron, and oxygen — a salt with elemental formula Na 2 B 8 O 13 or (Na +) 2 [B 8 O 13] 2−, also written as Na 2 O·4B 2 O 3. It is a colorless crystalline solid, soluble in water.
