Sodium nitrate is the chemical compound with the formula NaNO 3. This alkali metal nitrate salt is also known as Chile saltpeter to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter. Sodium nitrate is a white deliquescent solid very soluble in water. It is a readily available source of the nitrate anion, which is useful in several reactions carried out on industrial scales for the production of fertilizers, pyrotechnic

Sodium nitrate, also known as caliche, Chile saltpeter, and soda niter, is a chemical compound. It contains sodium and nitrate ions. Its chemical formula is NaNO 3.
Sodium nitrite is an inorganic compound with the chemical formula NaNO2. It is a white to slightly yellowish crystalline powder that is very soluble in water and is hygroscopic. From an industrial perspective, it is the most important nitrite salt. It is a precursor to a variety of organic compounds, such as pharmaceuticals, dyes, and pesticides, but it is probably best known as a food additive used in processed meats and in fish products.

- Occurrence and production
Nitrate is a polyatomic ion with the chemical formula NO− 3. Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate.
The ion is the conjugate base of nitric acid, consisting of one central nitrogen atom surrounded by three identically bonded oxygen atoms in a trigonal planar arrangement. The nitrate ion carries a formal charge of −1. This charge results from a combination formal charge in which each of the three oxygens carries a −2⁄3 charge, whereas the nitrogen...
A rich source of inorganic nitrate in the human diets come from leafy green foods, such as spinach and arugula. NO− 3 is the viable active component within beetroot juice and other vegetables. Drinking water is also a dietary source. Dietary nitrate supplementation delivers positive results when testing endurance exercise performance. Ingestion of ...
Nitrate salts are found naturally on earth in arid environments as large deposits, particularly of nitratine, a major source of sodium nitrate. Nitrates are produced by a number of species of nitrifying bacteria in the natural environment using ammonia or urea as a source of nitrogen and source of free energy. Nitrate compounds for gunpowder were h...
Nitrates are used as fertilizers in agriculture because of their high solubility and biodegradability. The main nitrate fertilizers are ammonium, sodium, potassium, calcium, and magnesium salts. Several million kilograms are produced annually for this purpose.
Nitrates are used as oxidizing agents, most notably in explosives, where the rapid oxidation of carbon compounds liberates large volumes of gases. Sodium nitrate is used to remove air bubbles from molten glass and some ceramics. Mixtures of the molten salt are used to harden some
Nitrate was also used as a film stock through nitrocellulose. Due to its high combustibility, the studios swapped to acetate safety film in 1950.
Almost all methods for detection of nitrate rely on its conversion to nitrite followed by nitrite-specific tests. The reduction of nitrate to nitrite is effected by copper-cadmium material. The sample is introduced with a flow injection analyzer, and the resulting nitrite-containing effluent is then combined with a reagent for colorimetric or elect...
It is also a weak reducing agent, being oxidized to nitrate. It contains nitrogen in its +3 oxidation state. It is toxic in large amounts. Occurrence. It is found in some vegetables. It is also found in some meat in small amounts. Otherwise, it is manmade. Uses. It is used in meat like ham to preserve it.
Sodium at standard temperature and pressure is a soft silvery metal that combines with oxygen in the air and forms grayish white sodium oxide unless immersed in oil or inert gas, which are the conditions it is usually stored in. Sodium metal can be easily cut with a knife and is a good conductor of electricity and heat because it has only one electron in its valence shell, resulting in weak metallic bonding and free electrons, which carry energy. Due to having low atomic mass and large ...
Sodium Nitrate is a resource. Sodium Nitrate (Na+) is a resource and one of the catalyst elements. An advanced catalyst, useful for charging defensive technologies such as shields or hazard protection. Created in a Refiner, or occasionally found in crystalline form on a planet's surface. Offers...
