What is the solubility of sodium tetraborate?

When the solution temperature is 0 degrees Celsius, the solubility in 100 grams of water is grams, and when it is 60 degrees Celsius, the solubility in 100 grams of water is grams.

Sodium tetraborate, also known as borax, is highly toxic and is a very important boron-containing mineral and boron compound, usually a white powder containing colorless crystals, soluble in water.

Borax has a wide range of uses, from cleaning agents, cosmetics, pesticides, to buffer solutions and other boron compounds. Borax often refers to the quiver of sodium tetraborate.

Sodium tetraborate, or borax, has the molecular formula Na2B4O H2O, which is highly toxic. It is a very important boron-containing mineral and boron compound. It is usually a white powder containing colorless crystals that is easily soluble in water.

Borax has a wide range of uses, from being used as a search cleaner, cosmetic product, insecticide, as well as in the preparation of buffer solutions and other boron compounds. Borax often refers to sodium tetraborate decahydrate, i.e., Na2B4O H2O, but commercially available borax is often partially weathered.

Summary. The solubility of boron is closely related to the presence of sodium ions. As the concentration of sodium ions increases, the solubility of boron increases significantly.

The solubility of boron is closely related to the presence of sodium ions. As the concentration of sodium ions increases, the solubility of boron increases significantly.

Fellow, I really didn't understand, I can be more specific.

This is because:1The borate ion B(OH)4- and sodium ion Na+ can form a solvent compound of sodium borate Na[B(OH)4], and the formation of this solvent compound increases the solubility of boron.

As the concentration of sodium ions increases, the production of sodium borate also increases, and the solubility of boron naturally increases. 2.The borate ion B(OH)4- carries 4 negative charges, while the sodium ion Na+ carries 1 positive charge.

Sodium ions can undergo an electrically neutralized reaction with borate ions to form charged sodium borate complexes such as Nab(OH)4, Na2B(OH)4+, etc. The formation of this complex also increases the solubility of boron. 3.

Due to the relatively small electronegativity of boron, the dissociation degree of boric acid in water is not high. However, when a large number of sodium ions are present, according to the conjugated acid-base pair theory, sodium ions can promote the dissociation of boric acid and generate more borate ions, thus also improving the solubility of boron. 4.

Sodium ions can change the ionic strength of the aqueous solution, which will affect the hydration between boric acid and water molecules, weaken the mutual fingering effect between boric acid and water molecules, make the boric acid cluster easier to dissociate, and indirectly increase the solubility of boron. In summary, the presence of sodium ions can promote the dissolution of boron in many ways, mainly by affecting the dissociation degree of boric acid, forming solvent compounds or complexes with borate ions, and changing the ionic strength of the solution to improve the solubility of boron. Therefore, there is a positive correlation between boron solubility and sodium ion concentration.

The solubility of boric acid is as follows:

Solubility in water: 0

Further information is as follows:

Boric acid, is an inorganic compound, the chemical formula is H3BO3, is a white crystalline powder, has a slippery feel, no odor, a large number of glass industry, can improve the heat resistance, transparency of glass products, improve mechanical strength, shorten the melting time, can also be used as anti-corrosion, disinfectant.

1. Use

It is widely used in the glass industry, which can improve the heat resistance and transparency of glass products, improve mechanical strength, shorten the melting time, and can also be used as anti-corrosion and disinfectant.

2. Storage method

It should be stored in a dry and clean warehouse, not stacked in the open air, and should be protected from rain or moisture. It should be transported in a boxcar, cabin or covered car, and should not be mixed with wet items and colored raw materials, and the means of transport must be dry and clean.

3. The application of collar spine domain - boric acid glass and glass fiber

It is used in the production of high-grade glass and glass fibers such as optical glass, acid-resistant glass, and organic boron glass, which can improve the heat resistance and transparency of glass, improve mechanical strength, and shorten melting time. B2O3 plays the dual role of flux and network formant in the manufacture of glass and glass fibers.

For example, in the production of glass fibers, the center warp of the cherry head reduces the melting temperature and thus facilitates wire drawing. In general, B2O3 can reduce viscosity, control thermal expansion, prevent leakage, improve chemical stability, and improve resistance to mechanical and thermal shock. In glass production where low sodium content is required, boric acid is often mixed with sodium borate (e.g., borax pentahydrate or anhydrous borax) to adjust the sodium-boron ratio in the glass.

This is important for borosilicate glass, as boron oxide exhibits good solubility at low sodium and high aluminum.

, application areas - boric acid enamel and ceramics

The enamel and ceramic industries are used in the production of glaze, which can reduce the thermal expansion of the glaze and reduce the curing temperature of the glaze, so as to prevent cracking and deglazing, and improve the gloss and fastness of the product. For ceramics and enamel glazes, boron oxide is a good flux and network former.

It can form glass (at low temperatures), improve the adaptability of the glaze, reduce viscosity and surface tension, increase the refractive index, improve mechanical strength, durability and wear resistance, and it is an important component of lead-free glaze. High boron frit matures quickly and forms a smooth glaze quickly, which is conducive to coloring. In the frit of the rapidly fired glazed bricks, B2O3 is introduced with boric acid to ensure the requirement of low sodium content.

Boric acid and sodium tetraborate are two different compounds.

Boric acid, also known as boric acid water bucket conjuge, with the chemical formula H3BO3, is an inorganic compound and one of the important products of boron. Boric acid can be heated into anhydrous boric acid, which is a white solid with good solubility and can form a stable acid-base buffer with it in water. Boric acid is mainly used in ceramics, glass, electronics industry, metallurgy and other fields, and can also be used as a fungicide, preservative, and agricultural applications such as the manufacture of boron fertilizer.

Sodium tetraborate, also known as borax, with the chemical formula Na2B4O7, is a colorless and odorless crystal that can be prepared by the reaction of boric acid and sodium carbonate. Sodium tetraborate is mainly used in glass processing, detergents, water treatment, pharmaceuticals and other chemical fields. Sodium tetraborate is also widely used in laboratories, such as chemical analysis, glass making, catalysis, and other fields.

So, while both boric acid and sodium tetraborate contain elemental boron, they are two different compounds with different properties and applications.
