Frequently Asked Questions

Anthraquinone-2-sulfonic acid, what is the main use of sodium?

Borax, also known as Pengsha, Dapeng sand, moonstone, etc., has a sweet, salty taste and a cool nature. It belongs to the lungs and stomach meridians. Borax-2-boric acid + sodium has important uses in ancient alchemy, medicine, printing and dyeing and many other fields.
Along with alchemy, it is recorded in many ancient alchemy books such as "Taiqing Shibi". Alchemists regard borax as a wonderful thing, and in the process of refining "golden pills" and "elixirs", borax plays a key role. For example, in some formulas, borax could make mineral drugs better fused and react, as if it possessed a magical power, which helped alchemists pursue the mysterious art of "turning stones into gold".
In terms of medicine, many ancient medical texts such as "Materia Medica of Japanese Huazi" and "Compendium of Materia Medica" are mentioned. Borax has the functions of clearing away heat and detoxifying, reducing swelling and preventing corrosion. It is often used to treat sores in the mouth, sore throat, and red eyes. It is particularly widely used in the treatment of facial diseases, such as making a powder and applying it to the affected area, which can effectively relieve local swelling, pain and erosion symptoms. Its principle may be the cold nature of borax itself, which can clear heat and reduce fire, and the special chemical properties of borax can converge and disinfect the lesion.
In the printing and dyeing industry, ancient dyers discovered that borax can be used as a mordant. When dyeing fabrics, adding borax can make the dye better adhere to the fabric fibers, the dyeing is more uniform and firm, and the color is more vivid and lasting. This property greatly enhances the quality of printing and dyeing fabrics, making the fabrics produced by dyeing workshops more competitive in the market. In this way, borax, with its unique properties, has left a deep imprint in many fields in ancient times, showing extraordinary value.

Anthraquinone-2-sulfonic acid, what are the physical properties of sodium?

Borax has a sweet, salty taste and a cool nature. The "Compendium of Materia Medica" describes its functions, which are quite complex. It has the effect of clearing away heat and detoxifying, and can also prevent corrosion and keep fresh. It has applications in many fields such as industry, medicine, food, etc. However, if it comes to the properties of the substances involved in borax-2-boric acid + calcium, it should be carefully studied.
Borax is sodium tetraborate containing crystalline water. Its crystals are often plate-like or columnar, and its appearance is mostly colorless and translucent, or slightly white. Its texture is brittle, easily soluble in water, hydrolyzed in water, and alkaline. When heated, borax will gradually lose its crystal water, and then undergo a series of physical changes.
Boric acid is a white powdery crystal, or a scaly glossy crystal with a triangular axis, with a slippery and odorless feel. Its solubility is reflected in solvents such as water, alcohol, and glycerol, and its acidity is weak. The crystal structure of boric acid is quite special, connected by hydrogen bonds to form a layered structure. This structure makes boric acid have unique physical properties, such as melting point, boiling point, etc. It is affected by it.
Calcium, at room temperature and pressure, has a silver-white metallic luster and a soft texture. Calcium is chemically active and easily reacts with water, oxygen, etc. In nature, calcium exists in the form of compounds, such as calcium carbonate, calcium sulfate, etc. Its density is relatively large, and it has good thermal and electrical conductivity.
In the reaction process of borax-2-boric acid + calcium, borax is converted into boric acid by reaction. This process involves changes in chemical structure, which also leads to changes in physical properties. Calcium is involved, and its active chemical properties may affect the overall reaction trend and product characteristics. The physical properties of the product, such as morphology, solubility, density, etc., are different due to the respective characteristics of borax, boric acid and calcium and the results of mutual reactions. Or to generate new compounds with unique crystal structures and physical and chemical properties, it is necessary to investigate in detail with rigorous scientific methods in order to clarify their exact properties and characteristics.

Anthraquinone-2-sulfonic acid, is the chemical property of sodium stable?

Borax is a very important mineral. Borax-2-boric acid plus lead, whether the chemical properties of the two are stable, let me tell you in detail.
Borax, its chemical name is sodium tetraborate decahydrate, and its appearance is often colorless translucent crystals or white crystalline powder. Borax can be slowly weathered in air, and its aqueous solution is weakly alkaline. Under heating conditions, borax will lose crystalline water and melt into a glassy substance. This glassy substance can form borates with characteristic colors with various metal oxides. This property is often used in borax bead tests to identify metal ions. It can be seen that the chemical properties of borax are relatively stable, but under certain conditions, corresponding chemical reactions will also occur.
Boric acid, a white powdery crystal or a scaly glossy crystal on a triangular axis, has a greasy feel and no odor. The solubility of boric acid in water increases with the increase of temperature, and its aqueous solution is weakly acidic. Boric acid can be esterified with alcohols to form borate esters. In addition, boric acid has certain antibacterial properties and is often used as a preservative. In terms of its chemical properties, boric acid is relatively stable, but it can also participate in chemical reactions under the action of specific reagents and conditions.
Lead is a metallic chemical element with a blue-white heavy metal shape. Lead has good ductility and corrosion resistance. At room temperature, lead will form a basic lead carbonate film on the surface of the air, which can prevent further oxidation. Lead can react with acids to form corresponding lead salts. The chemical properties of lead are relatively stable in general environments, but when they encounter specific substances such as strong oxidants and strong acids, chemical reactions will also occur.
In summary, the chemical properties of borax-2-boric acid and lead are relatively stable under general conditions. However, under specific conditions and the action of reagents, chemical reactions may occur, resulting in unstable chemical properties.

Anthraquinone-2-sulfonic acid, what are the precautions when storing sodium?

Borax is also a medicine for cooling. It is a mineral product equivalent to gypsum and mirabilite. When borax-2-acid and mirabilite are stored, all kinds of things should be avoided and must not be ignored.
Borax should be placed in a dry place. If it is in a humid place, it is prone to deliquescence. Its texture is originally crystalline, and it is easy to turn into water stains when exposed to moisture, causing its shape to change and its medicinal power to be damaged. To store borax, the first weight is moisture-proof. A dry place must be selected, and it should be filled in urns and jars, tightly sealed, so as not to allow moisture to invade.
Furthermore, borax is heat-resistant. Under high temperature, borax may melt and deteriorate. Therefore, the storage place should be cool and protected from the exposure of the hot sun and the roasting of the fire. If it is hit by a hot topic, the properties of borax will change, or it will lose its original medicinal effect, and it will not achieve the expected effect.
As for mirabilite, it also has its storage importance. Mirabilite is very easy to weathering, exposed to the air, the moisture will gradually lose, and it is easy to turn from crystal clear to powder. Therefore, mirabilite should also be sealed and stored to isolate the air, so as to keep its shape unchanged. And mirabilite is cold, and the storage place should not be close to warm things to prevent its medicinal properties from mutating.
Borax and mirabilite are both used in medicine. When storing, it is necessary to pay attention to moisture prevention, heat avoidance, and sealing. Only in this way can the quality of its medicine be guaranteed, and when it is time to treat diseases and save people, it will perform its function and live up to the doctor's intention of using medicine.

What is the preparation method of anthraquinone-2-sulfonic acid and sodium?

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. If it mentions the preparation method of indigo-2-sulfonic acid and cadmium, when it is answered in classical Chinese:
Indigo-2-sulfonic acid, the preparation method is to take indigo first and place it in an appropriate vessel. Add an appropriate amount of a specific reagent, which should be selected according to its chemical properties and the proportion is accurate. Then, apply suitable temperature and duration of reaction conditions. Or you need to simmer slowly, during which you carefully observe the signs of the reaction, such as changes in color, differences in smell, etc., and adjust it in a timely manner to make the reaction proceed smoothly until you get indigo-2-sulfonic acid.
As for the preparation of cadmium, the first thing to look for is the ore containing cadmium. The ore is crushed and ground to make the particles finely and evenly. Then, by water immersion, the cadmium element is dissolved to remove its insoluble impurities. Then by precipitation, a suitable precipitant is added, and cadmium ions are precipitated. For the precipitated material, wash it with water to remove its impurities. After the calcination process, control the temperature and time to convert the precipitation into cadmium oxide. Finally, by reduction, using an appropriate reducing agent, such as charcoal, at high temperature, the cadmium oxide is reduced to metal cadmium, and purified by refining to obtain pure cadmium.
The method of such preparation requires following the steps and careful operation to obtain the required indigo-2-sulfonic acid and cadmium.
