The structure of the tetrahydroxyborate ion ([B(OH) 4] −). This anion has a tetrahedral molecular geometry at the boron atom. The structure of the orthoborate ion ( [BO 3 ] 3− ).
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.
Tetrahydroxyborate is an inorganic anion with the chemical formula [BH 4 O 4] − or [B(OH) 4] −. It contributes no colour to tetrahydroxyborate salts. It is found in the mineral hexahydroborite, Ca(B(OH) 4) 2 · 2 H 2 O, originally formulated CaB 2 O 4 · 6 H 2 O. [2] It is one of the boron oxoanions, and acts as a weak base.
Sodium borohydride, also known as sodium tetrahydridoborate and sodium tetrahydroborate, [5] is an inorganic compound with the formula Na B H 4 (sometimes written as Na[BH 4]). It is a white crystalline solid, usually encountered as an aqueous basic solution. Sodium borohydride is a reducing agent that finds application in papermaking and dye ...
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.
Hexahydroborite is the end member of a series of natural metaborates with the general formula CaB 2 O 4 ·nH 2 O or CaO·B 2 O 3 ·nH 2 O with n varying from 0 to 6, the other end member being anhydrous calciborite CaB 2 O 4. [3] [4] The anion in the structure is tetrahydroxyborate, [B(OH 4)] −. The name comes from an interpretation of the ...
