Difference Between Nitrate and Nitrite

Main difference

Both words, nitrate and nitrite they are used interchangeably as they have fairly similar pronunciation and spelling. They share many similarities and this is why they sometimes intermingle. Both are the inorganic chemical compounds that have a composition of nitrogen and oxygen. The number of oxygen atoms really makes a difference as their structure, shape, and function change. Nitrites have two oxygen atoms and one nitrogen, while nitrates have three oxygen atoms and one nitrogen atom. Since there is only the difference of the oxygen atom, a nitrate can be converted to a nitrite and the opposite can also happen. A nitrate can be converted to a nitrate by undergoing the reduction process while nitrites can be converted to a nitrate by undergoing the oxidation process .

Base Nitrate Nitrite
number of atoms Nitrate is made up of three oxygen atoms and one nitrogen atom. Nitrite is made up of one nitrogen atom and two oxygen atoms.
Nitrogen oxidation number In nitrate, the oxidation number of nitrogen is +5. In nitrite, the oxidation number of nitrogen is +3.
acid formed Nitrate ions form nitric acid, which happens to be a strong acid. Nitrite ions form nitrous acid, which turns out to be a weaker acid.
Use The most common uses of nitrates are that they are used as a major component in fertilizers and explosives. One of the most prominent uses of nitrites is that it is used as a useful component for food preservation.

What is nitrate?

Nitrate is the polyatomic ion that is made up of nitrogen and oxygen. The ‘N’ at the beginning of ‘nitrate’ suggests that the influence of the nitrogen atoms influences and dominates the ion. It is made up of three oxygen atoms and one nitrogen atom, and is very stable compared to nitrite, and even the acid made from it, nitric acid is a strong acid. The most common uses of nitrates are that they are used as a major component in fertilizers and explosives. Nitrate is essential for plant growth and before the stable fertilizer industry, cattle fecal matter was used for plant growth as fertilizer. The complete cycle begins with the consumption of nitrogen from the atmosphere by the bacteria and then the decomposition of the bacteria, which results in the uptake of nitrate by the plants and then the animals eat the plants and then pass the nitrate through their faeces. The structure of the nitrate ion makes it quite more stable since it forms as the trigonal planar geometry, nitrogen is present in the center and is bonded to the three oxygen atoms.

What is nitrite?

Nitrite is the polyatomic ion that is made up of nitrogen and oxygen. The real difference between nitrate and nitrite is that nitrite is made up of one nitrogen atom and two oxygen atoms. Its structure makes the nitrite ion less stable than nitrate ions. Although, a nitrate can be converted to nitrite by undergoing the reduction process while nitrites can be converted to nitrate by undergoing the oxidation process. The molecular formula of nitrite is NO2 and it has a structure with a nitrogen atom between the two oxygen atoms. It has a molecular shape of bent molecular geometry. One of the most prominent uses of nitrites is that it is used as a useful component for food preservation. They have a great capacity to act as antagonists of bacteria,

Nitrate vs. Nitrite

  • Nitrate is made up of three oxygen atoms and one nitrogen atom, while nitrite is made up of one nitrogen atom and two oxygen atoms.
  • In nitrate, the oxidation number of nitrogen is +5, while in nitrite the oxidation number of nitrogen is +3.
  • Nitrate ions form nitric acid, which turns out to be a strong acid, on the other hand, nitrite ions form nitrous acid, which turns out to be a weaker acid.
  • The most common uses of nitrates are that they are used as an important component in fertilizers and explosives, on the other hand, nitrite is used as a preservative agent in various foods.
  • A nitrate can be converted to nitrite by undergoing the reduction process while nitrites can be converted to nitrate by undergoing the oxidation process.
