Molecular Formula: NaNO2 Molecule Weight: 69.0
CAS NO.:7632-00-0 Appearance:White or light yellow Fine Crystal

Property: White or a little buff fine crystal. The relative molecular weight is 69.0 and density is 2.168. It’s no
smell and a little saline taste, easy to be deliquescence and to dissolve in water. The melting point is 271℃
and decomposition temperature is 320℃. It has the strong oxidizing property, as well as reducing property.
It can slowly oxidize into sodium nitrite in the air, and will become diamino compound composed with
ammonia under low temperature.
