High Quality Sodium Nitrite 99.0%Min 7632-00-0 NaNO2 Sodium Nitrite Powder
Sodium nitrite is white to light yellow granular, rod or powder. It is hygroscopic. It is soluble in 1.5 parts of cold water, 0.6 parts of boiling water, and slightly soluble in ethanol. The relative density is 2.17. The melting point is 271°C.
The aqueous solution of sodium nitrite is alkaline, a strong oxidant and reductive. It will gradually oxidize in the air, and the surface will become sodium nitrate, which can be decomposed by heating to 320℃ or above, and it can also be oxidized by the oxidant; it will liberate brown when exposed to weak acid. Nitrogen dioxide gas; contact with organic matter and reducing agents can cause explosion or combustion, and release toxic and irritating nitrogen oxide gas; it can also be oxidized when exposed to strong oxidants, especially ammonium salts, such as ammonium nitrate, ammonium persulfate, etc. At room temperature, it can interact with each other to generate high heat, causing combustibles to burn. It is oxidizing. It can burn and explode in contact with organic matter, and emit toxic and irritating nitrogen peroxide and nitrogen oxide gases.
