  2. Sodium borate - Wikipedia

    en.wikipedia.org/wiki/Sodium_borate

    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.

  3. Borax - Wikipedia

    en.wikipedia.org/wiki/Borax

    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.

  4. Borate - Wikipedia

    en.wikipedia.org/wiki/Borate

    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 ...

  5. Disodium octaborate - Wikipedia

    en.wikipedia.org/wiki/Disodium_octaborate

    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.

  6. Disodium enneaborate - Wikipedia

    en.wikipedia.org/wiki/Disodium_enneaborate

    Disodium enneaborate is the traditional name for a salt of sodium, boron, oxygen, and hydrogen, with elemental formula Na 2 B 9 H 22 O 20 or Na 2 B 9 O 9 ·11H 2 O. It is the sodium borate with the highest boron/sodium ratio. [1]

  7. Tetraborate - Wikipedia

    en.wikipedia.org/wiki/Tetraborate

    Structure of the hydrated tetraborate (borax) ion, [B 4 O 5 (OH) 4] 2−. In chemistry, tetraborate or pyroborate is an anion (negative ion) with formula B 4 O 2− 7; or a salt containing that anion, such as sodium tetraborate, Na 2 B 4 O 7. It is one of the boron oxoacids, that is, a borate.

  8. Boron compounds - Wikipedia

    en.wikipedia.org/wiki/Boron_compounds

    Unlike silicates, boron minerals never contain boron with coordination number greater than four. A typical motif is exemplified by the tetraborate anions of the common mineral borax, shown at left. The formal negative charge of the tetrahedral borate center is balanced by metal cations in the minerals, such as the sodium (Na +) in borax. [1]

  9. Trisodium orthoborate - Wikipedia

    en.wikipedia.org/wiki/Trisodium_orthoborate

    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. However, "sodium orthoborate" has been used also for a compound with formula Na 4 B 2 O 5, which would correspond to an equimolar mixture of sodium metaborate NaBO 2 and trisodium borate proper.
