Barium Nitrate, Formula, Chemical Properties, Preparation, Uses

Barium Nitrate

Barium nitrate is an inorganic compound that the combination of the barium salt with the nitric acid. Barium nitrate is a colourless, water soluble and toxic substances. The nitrobarite is the rare mineral in the group of barium compounds. Commonly it has been used in the pyrotechnics. It can be exploded under the right conditions when it is reacted to heat. It is one of the non combustible chemicals.The systematic IUPAC name is known as Barium nitrate. The chemical or molecular formula of Barium nitrate is Ba(NO3)2. It is also known as barium salt or barium dinitrite.

Structural Formula

This is the structural formula of the Barium nitrate:

Barium Nitrate

Chemical Formula

The chemical formula or molecular formula is Ba(NO3)2.

Preparation Method

The barium nitrate can be prepared by the two methods. In the first method the barium carbonate is reacted with the nitric acid and it precipitate iron impurities to the surface. Then by using the filtration techniques this impurities are removed. Then the remaining solution is undergo to the evaporation process. After completed the evaporation it crystallizes to producing the barium nitrate. In the second method the barium sulfide is reacted with the nitric acid to producing the barium nitrate. But in this method the barium nitrate is decomposed and it gives the barium oxide, nitrogen dioxide and oxygen.
