Borax "dihydrate" has the formula Na 2 B 4 O 7 ·2H 2 O, which is actually anhydrous, with the correct formula Na 2 B 4 O 5 (OH) 4. It can be obtained by heating the "decahydrate" or "pentahydrate" to above 116-120 °C. [20] Anhydrous borax is sodium tetraborate proper, with formula Na 2 B 4 O 7. It can be obtained by heating any hydrate to 300 ...
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. The name is also applied to the hydrated ion [B 4 O ...
Sodium borate is a generic name for any salt of sodium with an anion consisting of boron and oxygen, ... (OH) 4 ·H 2 O: borax "pentahydrate" [2] 1:2:10: 0.333: Na 2 ...
Sodium pentaborate, more properly disodium decaborate, is a chemical compound of sodium, boron, and oxygen; a salt with elemental formula NaB 5 O 8, Na 2 B 10 O 16, or Na 2 O·5B 2 O 3. It is a colorless crystalline solid, soluble in water.
The product primarily consists of borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, and is named after the 20-mule teams that were used by William Tell Coleman's company to move borax out of Death Valley, California, to the nearest rail spur between 1883 and 1889.
The main borate anions are: tetrahydroxyborate [B(OH) 4] −, found in sodium tetrahydroxyborate Na[B(OH) 4]. orthoborate [BO 3] 3−, found in trisodium orthoborate Na 3 [BO 3] [BO 4] 5−, found in the calcium yttrium borosilicate oxyapatite Ca 3 Y 7 BO 4 (SiO 4) 5 O; perborate [B 2 O 4 (OH) 4] 2−, as in sodium perborate Na 2 [H 4 B 2 O 8]
People are ingesting borax. Also known by its chemical name sodium borate decahydrate, borax is a salt typically used to kill ants and boost laundry detergent, among other household cleaning needs ...
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.
