Nitrate (NO 3 1-) is a polyatomic ion. It is made up of one nitrogen and three oxygen atoms. It is part of many important molecules. Potassium nitrate is a common nitrate, used in fertilizers because plants need nitrates to live and grow.Some nitrates are explosive. People make large amounts of nitrates from ammonia.Nitrates are similar to nitrites. Nitric acid has the formula HNO 3 and has no overall charge, because the hydrogen ion is positive.otassium nitrate is a common nitrate, used in fertilizers because plants need nitrates to live and grow. Some nitrates are explosive. People make large amounts of nitrates from ammonia.
It is a readily available source of the nitrate anion (NO 3 â), which is useful in several reactions carried out on industrial scales for the production of fertilizers, pyrotechnics and smoke bombs, glass and pottery enamels, food preservatives (esp. meats), and solid rocket propellant.odium nitrate should not be confused with sodium nitrite, which is also a common food additive and preservative used for example, in deli meats. Less common applications include as an oxidizer in fireworks replacing potassium nitrate commonly found in black powder and as a component in instant cold packs.
