Sodium metabisulfite is white or yellow crystalline powder or small crystal, with a strong SO2 odor, soluble in water, the aqueous solution is acidic, when contacted with strong acid, SO2 is released to form corresponding salts, and it is oxidized to Na2S2O6 when placed in the air for a long time. Therefore, the product cannot be stored for a long time. Above 150 degrees Celsius, SO2 is decomposed.

Product Description "Sodium nitrite is an inorganic salt formed by the combination of nitrite ion and sodium ion. Sodium nitrite is easy to deliquescence, soluble in water and liquid ammonia, its aqueous solution is alkaline, slightly soluble in ethanol, methanol, ether and other organic solvents. Sodium nitrite has a salty taste and is sometimes used to make fake salt. When exposed to air, sodium nitrite reacts with oxygen to form sodium nitrate. When heated above 320 â??, it decomposes to form oxygen, nitrogen oxide and sodium oxide. Contact with organic matter is easy to burn and explode. chromatography. Drop analysis is used to determine mercury, potassium and chlorate. The use of sodium nitrite Diazotization reagent. Nitrosation reagent. Soil analysis. Serum bilirubin was measured in liver function test. Bleaching agent for silk and flax, metal heat treatment agent, corrosion inhibitor for steel, antidote for cyanide poisoning in laboratory.
