Main distinction – salt Fluoride vs Calcium Fluoride

Fluorides are chemical link containing fluoride ions (F–). Sodium fluoride and calcium fluoride space two such compounds. Sodium fluoride (NaF) is written of sodium cation and fluoride anion. It is a medication offered to protect against tooth degeneration caused through the low fluoride uptake. The is also used to treat youngsters in areas where fluoride contents in drink water is low. Calcium fluoride is composed of calcium cation and fluoride anion. It is present in the kind of a naturally emerging mineral called fluorite. The key difference in between sodium fluoride and also calcium fluoride is that sodium fluoride has one salt cation in association with one fluoride anion vice versa, calcium fluoride consists of one calcium cation in association through two fluoride anions.

What is sodium Fluoride

Sodium fluoride is an not natural salt written of sodium cations and also fluoride anions. The chemical formula of sodium fluoride is NaF. The molar massive of this link is 41.99 g/mol. The is a white to greenish heavy compound the is odorless.

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

Sodium fluoride occurs in nature in the form of villiaumite, which is a rare mineral. However, the is make industrially for its applications. The is produced by the neutralization of hydrofluoric acid (HF) using a suitable base. This involves the reaction in between HF and also NaOH. HF is acquired as a byproduct the the manufacturing of phosphoric acid from fluorophosphates by wet process.

HF + NaOH → NaF + H2O

Sodium fluoride is composed of salt cation and fluoride anion. The is offered as a medicine to stop tooth decay caused by the low fluoride uptake. The is used likewise to treat children in locations where fluoride content in drink water is low. NF additionally has countless applications in chemistry for synthesis and extractive metallurgy. In addition, it is offered in organic synthetic reactions, as a cleaning 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 of calcium fluoride is CaF2, and also the molar massive is 78.07g/mol. It appears as a white crystalline solid. However, the solitary crystals the Calcium fluoride are transparent.

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

CaCO3 + 2HF → CaF2 + CO2  + H2O

As one application, naturally arising fluorite is provided as a precursor because that the manufacturing of HF acid. This production process involves calcium fluoride reaction through sulfuric acid, which returns calcium sulfate (CaSO4) solid and also HF gas. Calcium fluoride is provided for the production of optical components such as windows, lenses, etc.
