General Information
The chemical formula is Ba (NO 3) 2. It consists of barium and nitrate ion. Barium nitrate is a highly hygroscopic structure that is soluble in water, which is a white hygroscopic structure at room temperature, and it is very toxic like other soluble barium compounds.
Production and Reactions
Barium nitrate; barium carbonate in nitric acid, which forms the impurity of iron for a crystallized precipitate, is melted into small pieces to give the first mixture. The second mixture consists of a mixture of barium chloride and a solution heated through sodium nitrate to cause barium nitrate crystals to separate. At high temperatures, barium nitrate disintegrates Barium oxide, nitrogen dioxide and oxygen:
2Ba (NO3) 2 heat? 2BaO 4NO2 O2
In nitric oxide environment, barium nitrate is produced by thermal decomposition. Soluble metal sulfates or sulfuric acid react with barium sulfate to form the product.
Usage areas
Explosive
It is used in the production of green fireworks in the industry. Baratol barium nitrate formation is an explosive composition consisting of TNT and binder.
Chemistry
Barium is used as a component in the production of peroxide.
