Sodium Nitrite
1. Name: Sodium Nitrite
Molecular formula: NaNO2
Molecular weight 69.00
2. Properties:
(1) General sodium nitrite: white fine crystals, or light yellow
(2) Dry powder sodium nitrite: white crystal, non-caking, loose,Specific gravity 2.168, odorless, slightly salty, easy to deliquesce and soluble in water, with a melting point of 271°C.
The decomposition temperature is 320°C; it has both oxidizing and reducing properties. It slowly oxidizes to sodium nitrate in the air, and easily forms nitrogen compounds with amino groups at low temperatures.
