Barium nitrite represented by the chemical formula Ba(NO2)2 or BaN2O4 [2] that bears the IUPAC name barium dinitride [3] is a white crystalline powder that is soluble in water and alcohol [6]. It is a barium salt and an ionic compound [2].

Barium Nitrite Identification

CAS Number 13465-94-6 [1]
PubChem CID 166820 [2]
ChemSpider ID 145952 [3]
EC Number 236-709-9 [1]

Barium Nitrite Formula

How to Make It

Barium nitrite can be prepared by decomposing silver nitrite by barium chloride [4].

2AgNO2 BaCl2 = 2AgCl Ba(NO2)2

It can also be made by pouring a warm solution of barium nitrate over lead and boiling the mixture for 1.5 to 2 hours [7].

Ba(NO3)2 2Pb = Ba(NO2)2 2PbO
