How to make borax water

There are two types of borax: industrial borax and medicinal borax. Borax is poisonous and harmful to the human body. It has a very high concentration and cannot be used for food. Borax water is borax diluted with water. The dissolved borax is borax water. We must pay special attention to it in our daily life. Once we come into contact with borax, we must seek medical treatment in time to avoid poisoning and serious consequences.

Borax is the most important compound of boron. When welding metals, people use borax to clean the metal surface. Boric acid is also commonly used as a disinfectant in hospitals. Boron is often listed as a rare element abroad. However, there are abundant borax mines in our country. Therefore, boron is not a rare element in our country, but an abundant element.

The chemical formula of borax should be written as Na2B4O5(OH)4·8H2O

Borax is a colorless crystal that weathers in the air and can be dehydrated into anhydrous sodium tetraborate when heated to 400-500°C. It melts into a glassy substance at 878°C. Because the melt contains acidic oxide B2O3, it can dissolve metal oxides. This property can be used to remove oxides on the metal surface when welding metals. Many metal oxides often show characteristic colors after dissolving in molten borax, such as cobalt metaborate Co(BO2)2 is blue, nickel metaborate Ni(BO2)2 is brown, chromium metaborate Cr(BO2)3 is emerald green, etc.

Borax has a wide range of uses. It can be used as a filler in laundry detergent and soap, and is also a raw material for making optical glass, enamel and porcelain glaze. It can also be used to make artificial gems, solder, etc. After being extracted and refined, it can be used as a heat-clearing and detoxifying medicine. It is cool in nature, sweet and salty in taste, and can treat sore throat, tooth decay, mouth ulcers, eye cataracts and other symptoms. Borax is also commonly used as a metal rust remover. In agriculture, borax can act as a boron fertilizer. Boron compounds such as borane can also be used as high-energy rocket fuel.
