Barium nitrite is a chemical compound, the nitrous acid salt of barium. It has the chemical formula Ba(NO2)2. It is a water-soluble yellow powder. It is used to prepare other metal nitrites, such as lithium nitrite.
Synthesis
Barium nitrite can be made by reacting barium nitrate with lead metal sponge, or by reaction of lead nitrite with barium chloride.[1]
Safety
Barium nitrite is toxic if ingested or inhaled, as both barium and the nitrite ion are toxic.[citation needed]
