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. It is used as chromogenic agent, anti microbial agent and preservative in meat products processing. It has been used in bleaching, electroplating and metal treatment, and is called industrial salt."

Product Description
"Sodium nitrate is an inorganic substance, which is easily soluble in water, liquid ammonia, methanol and ethanol, and its aqueous solution is neutral. It is obtained by absorbing nitrogen oxides with alkali solution in industrial production, then evaporating and crystallizing. It can be used for the preparation of nitric acid, sodium nitrite and catalyst in sulfuric acid industry.
It is the raw material for manufacturing potassium nitrate, mine explosive, picric acid, dye, etc. Nitrating agents for the manufacture of dye intermediates. The glass industry is used as defoamer, decolorizer, clarifier and oxidation flux for the production of various kinds of glass and its products. Enamel industry is used as oxidant and flux for preparing enamel powder. The machine industry is used as metal cleaning agent and black metal bluing agent. It is used in steel making and heat treatment of aluminum alloy in metallurgical industry. Light industry is used in the manufacture of cigarette combustion improvers. The pharmaceutical industry is used as a medium for penicillin. Chemical fertilizer industry is used as quick acting fertilizer for acid soil, especially for root crops such as beet and radish. It is also used as decolorizing agent of molten caustic soda. High purity analytical reagents, spectroscopic reagents and oxidants are also used in the synthesis of dyes and the manufacture of explosives and fireworks"
