BaNO32

BaNO32 is a nonstandard notation for barium nitrate, an inorganic salt composed of barium cations and nitrate anions. The accepted chemical formula is Ba(NO3)2. In typical sources, BaNO32 may appear as an informal or erroneous representation, but it refers to the same compound, Ba(NO3)2.

Properties and structure

Ba(NO3)2 forms as a white, crystalline solid at room temperature. It is highly soluble in water and acts as a strong oxidizing agent. Upon heating, it thermally decomposes and can release nitrogen oxides and oxygen, a behavior common to many metal nitrates. In solution, Ba2+ ions can serve as a test reagent in qualitative analysis for certain anions.

Production and occurrence

Ba(NO3)2 is produced industrially by reacting a soluble barium salt with nitric acid and then isolating the product by crystallization. Commonly encountered barium salts (for example, BaCl2 or Ba(NO3)2 itself in solution) can be used in metathesis reactions to yield Ba(NO3)2. Naturally occurring barium minerals do not consist of Ba(NO3)2; instead, nitrate salts are typically synthesized for commercial use.

Uses

Ba(NO3)2 is used as an oxidizer in pyrotechnics and fireworks, especially to produce a green flame color. It has historical utility as a laboratory reagent and as a source of Ba2+ ions in analytical chemistry. Its oxidizing properties also lead to applications in various specialty formulations, while handling typically occurs under conditions that limit contact with organic materials.

Safety

Barium nitrate is toxic if ingested or inhaled, and soluble barium compounds pose health hazards due to Ba2+ toxicity. It is an oxidizer, and should be kept away from reducing agents and organic materials to prevent hazardous reactions. Proper storage in a cool, dry place and appropriate personal protective equipment are advised.
