What is Borax? What are the chemical properties?

Borax, also known as coarse borax, is a colorless crystalline substance that is both soft and light. Borax has many familiar uses, such as disinfectants, fresh-keeping preservatives, water softeners, eyewashes, soap additives, ceramic glazes and glass raw materials, etc., and borax also plays an important role in industrial production. Colorless translucent crystals or white crystalline powder.

Odorless and salty. Lose all of the crystal water when you are specific to your specific gravity. Soluble in water, glycerin, slightly soluble in alcohol.

The aqueous solution is weakly alkaline. Borax can be slowly weathered in air. When melted, it becomes a colorless glass-like substance.

Borax has a bactericidal effect and is harmful to people when taken orally. CAS: 1303-96-4 Molecular Formula:

Sodium tetraborate, commonly known as: borax, the chemical formula of natural sodium tetraborate crystals: Na2B4O7 10H2O.

Sodium tetraborate is a colorless crystal, weathered in the air, heated to 400 500 can be dehydrated into anhydrous sodium tetraborate, and melted into glassy at 878. Because the melt contains the acidic oxide B2O3, it can dissolve metal oxides. This property can be used to remove oxides from metal surfaces when welding metals, many of which often exhibit their characteristic color when dissolved in molten borax.

The chemical formula of borax is Na2B4O7·10H2O.

Borax, also known as sodium tetraborate, with the chemical formula Na2B4O7, is a common boron-containing salt with the appearance of colorless crystals or white powder. It can inhibit the growth of yeast and mold, has been used as a preservative, can also inhibit the effect of tyrosinase, prevent tyrosine (tyrosine) oxidation to melanin, in recent years is often abused to prevent shrimp food blackening, maintain its color and luster.

Boric acids that are commonly found in the world:

Boric acid is a boron-containing inorganic weak acid, the appearance is white powder or transparent crystal, it feels greasy to the touch, slightly soluble in cold water, but the solubility will increase with the increase of temperature, at 20 degrees Celsius, 1 liter of water can be about soluble grams of boric acid.

Boric acid is actually quite common in nature: seawater itself contains boric acid and other salts; It can also be found in some of the most volcanic areas, such as Tuscany and Lipari Islands in Italy and Nevada in the United States. Sometimes, boric acid coexists with boron-bearing minerals, such as borax ores, interspersed with the mineral structure.

At present, borax is still relatively large in industrial use. It is mainly used in glass and enamel, and can also be used in herbicides, etc. For the role of borax, we should use it after understanding it clearly, so as to better ensure the safety of life.

Antibacterial effectIt has been reported that borax is a weak alkali, which has a weak antibacterial effect like boric acid. Use the plating method to make the medium contain 10% borax.

Borax, an inorganic compound, is generally written as Na2B4O7·10H2O, with a molecular weight. Borax 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 cleaning agents, cosmetics, pesticides, to buffer solutions and other boron compounds. Borax has high toxicity and is banned as a food additive in many countries around the world. If the human body ingests too much boron, it will cause accumulation poisoning of multiple organs.

Preparation method: Atmospheric pressure alkali hydrolysis method alkali hydrolysis method is based on the shortcomings of sulfuric acid method, such as low B2O3** rate, high cost, and serious equipment corrosion. In order to solve the B2O3 pollution, borax must be extracted and prepared from boron ore with high B2O3 content, and the remaining B2O3 in the mother liquor should be transferred to the borax as much as possible through the utilization of the mother liquor.

The alkaline hydrolysis method to process boronite and magnesium ore first requires ore roasting, and raw firing and overfiring will significantly reduce the alkaline hydrolysis rate. Boronite is used as the experimental raw material, roasted at a certain temperature, crushed, and then added NaOH solution for alkali lysis (the alkaline hydrolysis rate fluctuates generally at 70% 80%), filtered and washed with water to remove the residue, the filtrate is evaporated and concentrated, cooled and crystallized, and then dissolved with water, and then neutralized by baking soda, cooled and crystallized, and separated to obtain borax.
