Sodium Fluoride Formula – Equation and Problem Solved with Example

Sodium Fluoride is an inorganic salt that is taken as the important source of fluoride ion in a plenty of applications. The chemical formula for the compound could be writtenas the NaF and its molecular weight is 41.99 g/mol approximately. This is an ionic compound where one sodium cation is connected with one Fluoride anion. This is a solid salt exists in cubic crystal form and taken very much similar to the sodium chloride i.e. NaCl.

Sodium Fluoride Formula

The natural occurrence of compound can be felt in minerals in a small quantity only. The product can be prepared industrially by neutralizing hydrofluoric acid with bases such as sodium carbonate, or sodium bicarbonate, or sodium hydroxide etc.

HF + NaOH → NaF + H2O

If you would look at the physical properties of compound then the product is white crystalline solid and odourless too. It may exist in different colors from white to green based on the purity of metal. This is highly soluble in water and dissolves quickly into sodium and fluoride ions upon heating. This is a non-combustible metal and highly corrosive to the aluminium metal. When it decomposes to sodium and fluoride ions, it is releasing toxic gases and fumes of hydrogen fluoride.

The product is used as the fluorination agent in toothpastes and water supplies to maintain the dental health. It can be used for controlling corrosion, wood preservation, cleaning agent, chemical reagent, metallurgical process and more. The other common uses of the product are medical imaging, radio detector to identify various medical conditions.
