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.
1 Sodium nitrate is a type of salt, naturally found in Chile and Peru. 2  It can also be created in a lab. 3  Sodium nitrite is also a type of salt, but is not found naturally and is created in a lab or as a byproduct of two other chemical reactions (i.e. when sodium nitrate is added to food and reacts with existing chemicals).n reference to food, ânitrateâ really means sodium nitrate, but should really refer to sodium nitrite. While these are two completely different chemical compounds, they are often used interchangeably by those outside of the science realm.
