Sodium nitrate is a white deliquescent solid very soluble in water. It is a readily available source of the nitrate anion (NO 3−), which is useful in several reactions carried out on industrial scales for the production of fertilizers, pyrotechnics, smoke bombs and other explosives, glass and pottery enamels, food preservatives (esp. meats ...
One method uses molten sodium nitrate as the salt, and lead which is oxidized, while a more modern method uses scrap iron filings to reduce the nitrate. [4] [84] NaNO 3 + Pb → NaNO 2 + PbO. A more commonly used method involves the general reaction of nitrogen oxides in alkaline aqueous solution, with the addition of a catalyst. The exact ...
Curing salt is used in meat processing to generate a pinkish shade and to extend shelf life. [1] It is both a color agent and a means to facilitate food preservation as it prevents or slows spoilage by bacteria or fungus. Curing salts are generally a mixture of sodium chloride (table salt) and sodium nitrite, and are used for pickling meats as ...
2) is generally supplied by sodium nitrite or (indirectly) by potassium nitrate. Nitrite salts are most often used to accelerate curing and impart a pink colour. [18] Nitrate is specifically used only in a few curing conditions and products where nitrite (which may be generated from nitrate) must be generated in the product over long periods of ...
The most important sodium compounds are table salt (Na Cl), soda ash (Na 2 CO 3), baking soda (Na HCO 3), caustic soda (NaOH), sodium nitrate (Na NO 3), di- and tri- sodium phosphates, sodium thiosulfate (Na 2 S 2 O 3 ·5H 2 O), and borax (Na 2 B 4 O 7 ·10H 2 O). [7] In compounds, sodium is usually ionically bonded to water and anions and is ...
Molten salts (fluoride, chloride, and nitrate) can be used as heat transfer fluids as well as for thermal storage. This thermal storage is used in concentrated solar power plants. [8][9] Molten-salt reactors are a type of nuclear reactor that uses molten salt (s) as a coolant or as a solvent in which the fissile material is dissolved.
The main nitrate fertilizers are ammonium, sodium, potassium, calcium, and magnesium salts. Several billion kilograms are produced annually for this purpose. [1] The significance of nitrate extends beyond its role as a nutrient since it acts as a signaling molecule in plants, regulating processes such as root growth, flowering, and leaf ...
Prague powder #1 contains 6.25% sodium nitrite and 93.75% sodium chloride and is used for the preparation of all cured meats and sausages other than the dry type. [9] Prague powder #2 contains 1 ounce of sodium nitrite (6.25%) and 0.64 ounces sodium nitrate (4.0%) per pound of finished product (the remaining 14.36 ounces is sodium chloride) and ...
