Sodium Nitrate Properties – Structure and Preparation
Sodium nitrate is the chemical compound with the formula NaNO 3. This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter. … See more The first shipment of saltpeter to Europe arrived in England from Peru in 1820 or 1825, right after that country's independence from Spain, but did not find any buyers and was dumped at sea in order to avoid … See more Sodium nitrate is also synthesized industrially by neutralizing nitric acid with sodium carbonate or sodium bicarbonate: 2 HNO3 + Na2CO3 → 2 NaNO3 + H2O + CO2 HNO3 + NaHCO3 → NaNO3 + H2O + CO2 See more Studies have shown a link between increased levels of nitrates and increased deaths from certain diseases including Alzheimer's disease See more • Sodium nitrite See more The largest accumulations of naturally occurring sodium nitrate are found in Chile and Peru, where nitrate salts are bound within mineral deposits called caliche ore. Nitrates accumulate on land through marine-fog precipitation and sea-spray oxidation/desiccation … See more Most sodium nitrate is used in fertilizers, where it supplies a water-soluble form of nitrogen. Its use, which is mainly outside of high-income countries, is attractive since it does not alter the pH of the soil. Another major use is as a complement to ammonium nitrate in … See more • Archer, Donald G. (2000). "Thermodynamic properties of the NaNO3 + H2O system".

WebSodium Nitrate Boiling Point. The boiling point of NaNO3 is 380 °C (716 °F). Boiling point is the temperature at which a substance changes from a liquid to a gas at atmospheric pressure. NaNO3 is an ionic compound with strong intermolecular forces that hold its particles together. These intermolecular forces require a high amount of energy to ... WebBoiling point: 882.940°C, 1621.292°F, 1156.090 K Block: s Density (g cm −3) 0.97 ...
