Sodium nitrite (sodium nitrogen) / bag 25kg

Description

Sodium nitrogen-acid h (sodium nitrite) is a colorless or light yellow crystalline substance spanning in air. The solubility of sodium nitrogen-acid in water at 22 s is 45.07%. A saturated sodium solution of nitrogenous sodium boils at 128 C. Density - 2.17 g / cm3. Melting point 271 C. When heated above 320 s decomposes.Sodium nitrogenous is strongly poisonous, when inside the body, paralysis can cause paralysis of the Vasomotor Center and the formation of methemoglobin. The aqueous sodium sodium solutions have an alkaline reaction. Sodium nitride - oxidizer of moderate power. Acid decomposes with the release of nitrogen oxides.Sodium nitrogenous is obtained by absorbing nitrogen oxides with alkaline solutions, followed by evaporation of the solution. When the sodium is cooling, the nitrogenous crystallizes is crystallized from the solution, and at the same time the sodium-sodium nitrogen remains in the royaltics.Sodium nitrogenous is used as a food additive E250 in the food industry for two purposes: as an antioxidant, and as an antibacterial agent that prevents the growth of the pathogen of botulism. When entering into interaction with the protein of meat, gives meat products a characteristic pinkish color. In the construction of sodium, nitrogenous is used as an anti-corrosive additive to concrete in the production of building products and structures, as an atmospheric corrosion inhibitor.Sodium nitrogenic acid is also used in the production of diazo-dyes, when processing the surface of the metal during phosphating, in the production of rubber, as a panofor in the production of gas-filled explosives. Sodium nitrogenous is also used in medicine and veterinary medicine as a vasodilator, bronchhalytic, laxative, as well as antidot with cyanide poisoning.
