NaNO2 Sodium Nitrite 25 KG / BAG White Powder Used as Preservative
Sodium nitrite (NaNO₂) is an inorganic salt formed by the combination of nitrite ions and sodium ions. Sodium nitrite is easily deliquescent and soluble in water and liquid ammonia. Its aqueous solution is alkaline with a pH of about 9. It is slightly soluble in organic solvents such as ethanol, methanol. Sodium nitrite has a salty taste and is also used to make fake table salt. Sodium nitrite reacts with oxygen to form sodium nitrate when exposed to air. If heated to above 320°C, it decomposes to form oxygen, nitrogen oxides, and sodium oxide. It is easy to burn and explode when in contact with organic matter.
