Main distinction – salt Fluoride vs Calcium Fluoride

Fluorides room chemical link containing fluoride ions (F–). Salt fluoride and also calcium fluoride room two such compounds. Sodium fluoride (NaF) is written of salt cation and also fluoride anion. The is a medication supplied to avoid tooth degeneration caused through the short fluoride uptake. It is likewise used come treat youngsters in locations where fluoride content in drink water is low. Calcium fluoride is composed of calcium cation and fluoride anion. It is current in the kind of a naturally developing mineral dubbed fluorite. The main difference between sodium fluoride and also calcium fluoride is that sodium fluoride includes one sodium cation in association with one fluoride anion whereas calcium fluoride consists of one calcium cation in association v two fluoride anions.

What is salt Fluoride

Sodium fluoride is an not natural salt composed of sodium cations and also fluoride anions. The chemistry formula of sodium fluoride is NaF. The molar fixed of this link is 41.99 g/mol. The is a white come greenish hard compound that is odorless.

The melting suggest of salt fluoride is 993 °C, and also the boiling allude is 1,704 °C. Sodium fluoride is an ionic compound. This link exists in a cubic, crystalline structure that is similar to the framework of sodium chloride; NaCl.

Figure 1: sodium Fluoride Ionic Structure


Sodium fluoride occurs in nature in the type of villiaumite, which is a rarely mineral. However, that is make industrially for its applications. It is developed by the neutralization the hydrofluoric mountain (HF) using a perfect base. This requires the reaction between HF and NaOH. HF is obtained as a byproduct the the production of phosphoric acid from fluorophosphates by wet process.

HF + NaOH → NaF + H2O

Sodium fluoride is created of salt cation and fluoride anion. It is used as a medication to stop tooth degeneration caused by the short fluoride uptake. The is used additionally to treat children in locations where fluoride content in drinking water is low. NF additionally has countless applications in chemistry for synthesis and also extractive metallurgy. In addition, that is used in organic synthetic reactions, together a clean agent and also as a poison because that plant-feeding insects.


What is Calcium Fluoride

Calcium fluoride is an inorganic salt created of calcium cation and fluoride anions. The chemistry formula that calcium fluoride is CaF2, and the molar massive is 78.07g/mol. It shows up as a white crystalline solid. However, the solitary crystals the Calcium fluoride room transparent.

The melting allude of calcium fluoride is 1,418 °C, and the boiling suggest is 2,533 °C. Calcium fluoride occurs normally as fluorite mineral. It has actually a deep shade due come the presence of various impurities. It is abundant however is greatly used because that the production of HF acid. High purity Calcium fluoride is industrially created by dealing with calcium lead carbonate (CaCO3) through hydrofluoric acid (HF).

CaCO3 + 2HF → CaF2 + CO2  + H2O

As one application, naturally arising fluorite is used as a precursor for the production of HF acid. This production procedure involves calcium fluoride reaction v sulfuric acid, which returns calcium sulfate (CaSO4) solid and also HF gas. Calcium fluoride is offered for the manufacturing of optical contents such as windows, lenses, etc.

Difference in between Sodium Fluoride and also Calcium Fluoride

Definition

Sodium Fluoride: sodium fluoride is an inorganic salt created of a sodium cation and a fluoride anion.

Calcium Fluoride: Calcium fluoride is an not natural salt created of a calcium cation and also fluoride anions.

Chemical Formula

Sodium Fluoride: The chemical formula of sodium fluoride is NaF.

Calcium Fluoride: The chemistry formula of calcium fluoride is CaF2.

Molar Mass

Sodium Fluoride: The molar mass of sodium fluoride is 41.99 g/mol.

Calcium Fluoride: The molar massive of calcium fluoride is 78.07g/mol.

Melting point and boil Point

Sodium Fluoride: The melting point of salt fluoride is 993 °C, and the boiling allude is 1,704 °C.

Calcium Fluoride: The melting allude of calcium fluoride is 1,418 °C, and the boiling suggest is 2,533 °C.

Occurrence

Sodium Fluoride: salt fluoride wake up in nature in the kind of villiaumite, i beg your pardon is a rare mineral.

Calcium Fluoride: Calcium fluoride occurs normally as fluorite mineral.

Uses

Sodium Fluoride: sodium fluoride is largely used as a medication because that tooth decay.

Calcium Fluoride: Calcium fluoride is largely used together a precursor to produce HF acid.

Production

Sodium Fluoride: sodium fluoride is created by the reaction in between HF and also NaOH.

Calcium Fluoride: Calcium fluoride is industrially developed by dealing with calcium lead carbonate (CaCO3) v hydrofluoric mountain (HF).

Conclusion

Sodium fluoride and calcium fluoride room fluoride salts. The key difference in between sodium fluoride and calcium fluoride is that salt fluoride includes one sodium cation in association v one fluoride anion vice versa, calcium fluoride has one calcium cation in association through two fluoride anions.
