Production of Barium nitrate

Barium dinitrate is produced by two processes that start with the source component for barium viz carbonate.

Method 1:

Dissolve barium carbonate (BaCO3) in nitric acid (HNO3)Allow the precipitation of iron impuritiesSeparate the impurities by filtrationEvaporationCrystallization.

Method 2:

It is obtained by combining barium sulfide (BaS) with nitric acid (HNO3). At higher temperatures, barium nitrate (Ba(NO3)2) decomposes khổng lồ barium oxide (BaO):

2Ba(NO3)2 → 2BaO + 4NO2 + O2

Health hazards

Inhaling or contact of Nitrobarite with skin or eyes can cause irritation. Swallowing results in excessive salivation, colic, convulsive tremors, elevated blood pressure, vomiting, diarrhea, and hard pulse. It may also lead khổng lồ hemorrhages in the intestines, kidneys, và stomach. Also, muscular paralysis may occur.

Frequently Asked Questions

What are the uses of barium nitrate?

Barium nitrate is used in the manufacture of substances containing barium oxide. This compound is also used in the barium oxide production process, in the vacuum tube industry và in pyrotechnics for green fire. Barium nitrate has also been a key ingredient in the explosive charge “SR 365”.

What happens when barium nitrate is heated?

When burned, barium nitrate emits a green flame. It decomposes khổng lồ barium oxide, oxygen, & nitrogen dioxide when heated. This converts barium nitrite into nitric oxide. Lớn produce barium sulfate it combines with either sulfate or sulfuric acid.
