According to him, the physical properties of borax hydrate are as follows:
Borax hydrate, usually in the form of colorless translucent crystals or white crystalline powder. Its touch is delicate, and it looks clean and pure. At room temperature, it is relatively stable, but when heated, it will slowly lose crystal water.
In terms of solubility, borax hydrate has a certain solubility in water, and its solubility increases significantly with increasing temperature. In hot water, more borax hydrate can be dissolved to form a uniform solution; in cold water, the solubility is relatively small.
The density of borax hydrate is slightly larger than that of common water, because its molecular structure contains ions of boron, sodium and other elements in addition to water, resulting in an increase in its unit volume mass.
Furthermore, borax hydrate has a certain degree of hygroscopicity. In high humidity environments, it is easy to absorb moisture in the air, causing its own deliquescence, and its appearance may gradually change from dry crystals or powders to a wet state.
In addition, the aqueous solution of borax hydrate is weakly alkaline. This is because borax will undergo hydrolysis in water, generating hydroxide ions, which makes the solution alkaline. Although this alkalinity is not extremely strong, it is still sufficient to affect the properties of certain substances, such as neutralization reactions with acids.
These physical properties of borax hydrate make it unique in many fields and play an important role in industry, medicine, and scientific research.

Alas! Whether the chemical properties of the - 4 - boron sulfate compound are stable or not, it is a question that needs to be investigated in detail.
Boron sulfate complex, its properties may be unique due to the combination of boron and sulfate. Boron, with non-metallic properties, often shows a special valence state and bonding mode in compounds. Sulfate, with its stable structure, also affects the properties of compounds.
To know the chemical stability of this compound, it is necessary to observe its reaction under different conditions. At room temperature and pressure, without the intervention of strong external chemical reagents or energy, this compound may remain relatively stable. However, in case of high temperature, the chemical bonds inside the boron sulfate compound may be affected, causing it to decompose or undergo other chemical changes. High temperature can increase the kinetic energy of molecules, making chemical bonds more susceptible to fracture.
And in different pH environments, the stability of boron sulfate compounds is also different. In strongly acidic environments, sulfate may interact with hydrogen ions, and the coordination environment of boron may also change, which in turn affects the stability of the whole complex. In strongly alkaline environments, hydroxide ions may attack boron sulfate compounds, causing chemical reactions and destroying their original structures.
And when boron sulfate compounds come into contact with other chemicals, their stability also needs to be considered. In case of strong oxidizing agent or strong reducing agent, the valence state of boron or sulfur in the compound may change, and the properties of the compound will change.
Therefore, the chemical stability of boron-sulfuric acid compounds cannot be determined in one word, but depends on the comprehensive action of many factors. It must be tested and observed in detail under different conditions to find out.

The synthesis method of borax hydrate has various wonderful methods, all of which have unique ingenuity.
One method is to use borax as the basis, put an appropriate amount of borax in the kettle, slowly inject purified water, and cook slowly over a slow fire. During this period, you need to keep stirring with a wooden spoon to make sure that the borax is completely dissolved. When it is completely dissolved, the solution is clarified, and then move the kettle to a cool place and let it stand for a while. At this time, it can be seen that in the solution, there is a gradual crystallization of precipitation, which is borax hydrate. This process needs to pay attention to the urgency of the heat. If the fire is fierce, the solution is easy to boil and splash, and if the fire is small, the borax is difficult to dissolve, which is not a good method. < Br >
Another method, first take boric acid, put it in a porcelain bowl, slowly add soda ash, stir while adding, so that it fully reacts. After the reaction is completed, the mixture is obtained. Then the mixture is dissolved in an appropriate amount of water, and then filtered with filter paper to remove impurities. The filtrate is put into another purifier, evaporated and concentrated, and when the water is gradually reduced, it is cooled and left to stand, and the borax hydrate crystallizes. The key to this method is the ratio of boric acid to soda ash. If the ratio is improper, the product will be impure.
Another method is quite delicate. The boron-magnesium ore is used as the starting material, and it is first crushed and ground to make the particles fine. Treated with sulfuric acid to obtain a solution containing boron. After removing impurities, an appropriate amount of alkali is added to adjust the pH of the solution. Then through evaporation, crystallization and other steps, borax hydrate can be obtained. Although this process is complicated, it can be started from ore, and the raw materials are easy to find, which is quite practical.
The above methods have their own advantages and disadvantages. In actual operation, it is necessary to carefully choose according to the availability of raw materials and the purity of the product.

There are many points to be paid attention to when storing and transporting the - 4 - boric acid aqueous solution compound.
This compound has certain chemical properties. When storing, it needs to be stored in a dry and well-ventilated place. Because it is susceptible to moisture, if the storage environment is humid, or it occurs deliquescence and other conditions, its chemical composition and properties will be changed, which will affect the subsequent use effect. And it should be avoided to co-store with strong oxidants, strong alkalis and other substances to prevent violent chemical reactions from occurring and causing danger.
During transportation, ensure that the packaging is intact. The packaging needs to be able to withstand certain external shocks and bumps to prevent the leakage of boric acid aqueous solution due to package damage. The means of transportation should also be kept clean and dry, and there should be no other residual substances that may react with it. At the same time, the transportation temperature should be maintained in an appropriate range. If the temperature is too high, or the molecular movement inside the compound is intensified, causing unstable changes; if the temperature is too low, it may freeze and destroy the original structure.
Furthermore, whether it is storage or transportation, it must strictly follow the relevant chemical management regulations and standards. Operators need to be professionally trained and familiar with the characteristics of the compound and corresponding precautions to prevent safety accidents caused by improper operation. In this way, the safety and stability of boric acid aqueous solution compounds during storage and transportation can be ensured.
