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.

Potassium nitrate is a chemical compound with the chemical formula KNO3. It is an ionic salt of potassium ions K+ and nitrate ions NO3â, and is therefore an alkali metal nitrate. It occurs as a mineral niter and is a natural solid source of nitrogen. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter or saltpetre. Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks.
