Of course, an increased fluorine content can lead to fluorosis, but, according to authoritative studies, fluoridation of water cannot be the reason for the development of this pathology. But do not worry. For example, sodium fluoride is used as a medication. As mentioned above, fluoride can be used to prevent caries. Another method of preparation is the thermal decomposition of difluorohydrate and some complex salts. The chemical formula of sodium fluoride is NaF. It is a colorless or white solid that is readily soluble in water. In nature, this substance exists mainly in the form of the mineral williomite. When simple fluorine is oxidized with sodium bromate or other oxidizing agents containing sodium, sodium fluoride can be obtained as a product. Since the chemical bond of sodium fluoride is ionic, it is highly soluble in water, and even better - in hydrogen fluoride. Some fluorides (for example, calcium fluoride) are insoluble in water, so you can use the precipitation method to convert all the fluoride into a precipitate. Sodium fluoride is a chemical that consists of a combination of positively charged sodium ions and negatively charged fluoride ions. Often it is used in the metallurgical industry for cleaning metal surfaces, as well as during their melting and soldering. It penetrates well into wood and protects it from decay. This helps the bones to mineralize more stably. When reacted with hydrofluoric acid, difluorohydrate is formed. It is also used in the synthesis of certain chemical compounds, in particular freons and insecticides.

Sodium fluoride protects the teeth from acid demineralization while preventing tooth decay by bacteria while strengthening tooth enamel. In production, they are subjected to alkaline hydrolysis, as a result of which sodium fluoride is released in the reaction mixture. A child needs 5 times more. Fluorine is a fairly important trace element in the human body, without which its normal vital activity is impossible. To do this, usually replace the water source or just carry out the filtration. Osteosclerosis occurs, in which, unlike osteoporosis, bone density becomes higher than normal, which leads to a decrease in their elasticity. It is a condition manifested by white lines, pitting, or discoloration of teeth resulting from changes in tooth … Therefore, there is still debate about the use of fluorides as additives for toothpaste. Sodium fluoride has good antiseptic properties, so it is sometimes added to detergents. The substance is sometimes added to cement, making concrete resistant to acids, and to lubricants to increase heat-resistant qualities. In nature, this substance exists mainly in the form of the mineral williomite. Over-the-counter solutions of 0.05% sodium fluoride (230 ppm fluoride) for daily rinsing are available for use by persons older than 6 years of age. Although in recent years, some low-quality studies have begun to appear, suggesting the opposite. As can be seen from the chemical formula, sodium fluoride is a typical salt, so it enters into exchange reactions with other salts if a precipitate or gas is formed as a result of the reaction. It is a common source of fluoride in the production of pharmaceuticals and is used to prevent dental cavities. The introduction of vitamins C and D, as well as calcium gluconate, may help. Common Uses of Sodium Fluoride | Livestrong.com. When considering the chemical structure of sodium fluoride, it is composed of … But this remedy has a drawback due to which sodium fluoride is rarely used - it is easily washed out of wood during rains, as this salt is highly soluble in water. After enamel bleaching, remineralization is carried out with calcium gluconate solution. Sodium fluoride is an inorganic compound, a salt of hydrofluoric acid and sodium. The addition of sodium fluoride to fluoride-deficient municipal water supplies has been observed to reduce the incidence of caries by as much as 65 percent. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Fluorine ions stop glycolysis (glucose oxidation), so sodium fluoride is used for biochemical studies. https://www.britannica.com/science/sodium-fluoride. Sodium Fluoride Structure – NaF Today scientists are investigating…, Sodium fluoride is commonly added to drinking water in order to reduce the incidence of dental caries in children. By passing water through alumina, bone meal or bone coal, fluoride can also be removed from the water. Thanks to this process, the risk of caries is greatly reduced, especially among children. In adults, there is a risk of developing osteoporosis. But ordinary water does not always contain such an amount, so you have to increase it artificially. With an increased fluoride content in the body, fluorosis can occur. This is due to the fact that fluoride destroys bacteria that can dissolve tooth enamel and cause tooth decay. Their composition may be different depending on the ratio of reagents. Sodium fluoride is an inorganic compound, a salt of hydrofluoric acid and sodium. Filters operating on the principle of reverse osmosis remove almost all fluorine, and distillation purifies water completely. You can also remove foods that contain a lot of fluoride from the diet: sea fish, animal oil, spinach. In the latter case, gastric irritation can occur, up to an ulcer. The trade names for fluoride preparations are Sodium Fluoride, Sodium Fluoratum and Ossin. Sodium fluoride solutions are used with hard water insoluble compounds of calcium and magnesium fluoride can form. Sodium fluoride is a chemical compound. They are prescribed for a lack of fluoride in the body, in particular with osteoporosis. Most often, a three percent solution is used. It is used in trace amounts in the fluoridation of drinking water, toothpaste, in metallurgy, as a flux, and is also used in pesticides and rat poison.
