99% Purity Sodium Nitrite White Or Light Yellow Crystals Industrial Grade NaNO2
Sodium nitrite is white to light yellow granular crystal or powder, tasteless, easily deliquescent, toxic, slightly soluble in alcohol, and aqueous solution is alkaline, PH value of about 9. Relative density (water =1g/cm3) : 2.17g/cm3; Melting point: 271℃; Boiling point 320℃ (decomposition).
Sodium nitrite is a strong oxidant and reductive, will gradually oxidize in the air, the surface becomes sodium nitrate, can also be oxidized by the oxidant; Brown nitrogen dioxide gas is released when decomposed by weak acid. Contact with organic matter, reducing agent can cause explosion or combustion, and release toxic excitant nitrogen oxide gas; In the case of strong oxidants can also be oxidized, especially ammonium salt, such as ammonium nitrate, ammonium persulfate and so on at room temperature, that can interact with high heat, causing combustible combustion.
