什么是氟化钠?
Sodium fluoride is an inorganic compound, and it has the chemical formula NaF. A synonym for this compound is Florocid. Also, it is a colourless solid that readily dissolves in water. The molar mass of sodium fluoride is 41.98 g/mol. And, the melting point is 993 °C, while the boiling point is 1,704 °C. Besides, the crystal structure of sodium fluoride is a cubic crystal system.
此外,关于其应用,氟化钠是药品和牙膏中的重要成分。而且,它可以防止牙齿中的空腔。这种化合物自然出现以紫红色岩的形式,这是一种罕见的矿物质。但是,它可以用于其应用程序。我们可以通过中和HF酸产生氟化钠。在这里,酒精可用于沉淀NAF。该过程涉及HF和NaOH之间的反应。HF作为通过湿法从荧光磷酸盐产生磷酸的副产品获得。
Furthermore, sodium fluoride contains sodium cation and fluoride anion. Due to the presence of fluoride ions, this compound is useful as a medication to prevent tooth decay caused by low fluoride uptake. It is also used to treat children in areas where the fluoride content in drinking water is low. NF has many applications in chemistry for synthesis and extractive metallurgy. In addition, it is used in organic synthesis reactions, as a cleaning agent and as a poison for plant-feeding insects.
What is Sodium Monofluorophosphate?
Sodium monofluorophosphate is an inorganic compound having the chemical formula Na2po3F. The molar mass of this compound is 143 g/mol. And, it is commonly abbreviated as MFP. Also, it is a salt compound which is colourless, odourless, and readily dissolves in water. However, it is insoluble in organic solvents such as ethanol and ether. It appears as a white powder when produced industrially. Application-wise, it is a common ingredient in toothpaste.
In the industrial-scale production, MFT is produced via the reaction between sodium fluoride and sodium metaphosphate. Also, as an alternative method, it can be produced by treating tetrasodium phosphate with hydrogen fluoride.
When considering tooth decay problems, MFT acts as a fluoride source that comes from toothpaste. It can release fluoride via the hydrolysis of the compound. This fluoride can protect teeth from bacteria that cause dental cavities.
What is the Difference Between Sodium Fluoride and Sodium Monofluorophosphate?
氟化钠和单氟磷酸钠是牙膏中的重要成分。氟化钠和单氟磷酸钠之间的关键区别在于,氟化钠含有氟化钠阳离子,而单氟磷酸钠由钠,氟,磷和氧原子组成。
Below infographic tabulates the differences between sodium fluoride and sodium monofluorophosphate.
概括– Sodium Fluoride vs Sodium Monofluorophosphate
Sodium fluoride and sodium monofluorophosphate are important ingredients in toothpaste due to the ability to heal disorders regarding tooth. The key difference between sodium fluoride and sodium monofluorophosphate is that sodium fluoride contains sodium cations with fluoride anions, whereas sodium monofluorophosphate is composed of sodium, fluorine, phosphorous and oxygen atoms.
