Infobox references. Sodium nitrate is the chemical compound with the formula Na N O 3. This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [ 4 ][ 5 ] to distinguish it from ordinary saltpeter, potassium nitrate.
Sodium nitrite is an effective corrosion inhibitorand is used as an additive in industrial greases,[5]as an aqueous solution in closed loop cooling systems, and in a molten state as a heat transfer medium. [6] Food additive and preservative. [edit] Sodium nitrite is used to speed up the curingof meat,[7]inhibit the germination of Clostridium ...
Curing is any of various food preservation and flavoring processes of foods such as meat, fish and vegetables, by the addition of salt, with the aim of drawing moisture out of the food by the process of osmosis. Because curing increases the solute concentration in the food and hence decreases its water potential, the food becomes inhospitable ...
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. [ 1 ] Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate.
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 ...

Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. [ 1 ] The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature. The name nitrite also refers to organic compounds having the –ONO group, which are esters of nitrous acid.
Infobox references. Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O 3. It is an ionic salt of potassium ions K + and nitrate ions NO 3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US). [ 5 ]
