Nitrate vs Nitrite: Understanding the Difference

6 Difference Between Nitrite and Nitrate

The main difference between nitrite and nitrate is the presence of an oxygen atom bonded to the nitrogen atom in their chemical structure. 

S.NO.	Nitrite	Nitrate
1.	Nitrite has an oxygen atom bonded to the nitrogen atom in the form of a nitrite group (-NO2).	Nitrate has an oxygen atom bonded to the nitrogen atom in the form of a nitrate group (-NO3).
2.	Nitrite is characterized by the presence of a nitrite group (-NO2).	Nitrate is characterized by the presence of a nitrate group (-NO3).
3.	Nitrite is more reactive than nitrate due to the presence of the nitrite group, which can undergo reactions with other molecules.	Nitrite is less reactive.
4.	Nitrite has a lower boiling point than nitrate due to the presence of the nitrite group, which can form hydrogen bonds with other molecules.	Nitrite has a higher boiling point.
5.	Nitrite is more polar than nitrate due to the presence of the nitrite group, which can form hydrogen bonds with other molecules.	Nitrite is less polar.
6.	Nitrite is typically produced through the reduction of nitrate.	Nitrate is produced through the oxidation of ammonia or nitrite.
