Question

Fill in the blanks: Nitrite is….Nitride is…Nitrate is…?

Answer 1

Hint: Before solving this question, we should first know about Nitrite, Nitride, and Nitrate. Nitrite is the salt of nitrous acid. Nitride is a compound with a more electropositive element. Nitrate is a polyatomic ion.

Complete answer:
Nitrite
The chemical formula of Nitrite is $N{O_2}^{-}$. It results to be very useful in the pharmaceutical and chemical industries. It can be prepared when nitrous fumes are passed into an aqueous solution of Sodium hydroxide. Then recrystallization occurs for purifying the product. Organic compounds that have -ONO group are esters of Nitrous acid can also be referred to as Nitrite.
Nitride
The chemical formula of Nitride is $N^{3-}$
It is a compound of nitrogen (Oxidation state of it is 3). It is a huge class of compounds that has different characteristics, properties, and uses. It shouldn’t be kept in a protic solution because the nature of it is so basic that it gets protonated easily and has an ionic radius around 140 pm.
Nitrate
The chemical formula of nitrate is $N{O}_3^{-}$. The salts which have this ion are known as nitrates. Mostly all Inorganic nitrates are water-soluble. Bismuth oxynitrate is an insoluble nitrate. They are used in fertilizers and explosives.
So, Nitrite is $N{O_2}^{-}$
      Nitride is $N^{3-}$
      Nitrate is $N{O}_3^{-}$

Note:
Uses of Nitrite-
As a chemical precursor: It is required for the Diazotization process which helps in the preparation of Azo dyes and other colorants.
In Food preservation and biochemistry: It gives food an attractive color and also helps to fasten the curing of meat.
Uses of Nitride-
Compounds of it are used to cut materials and hard coatings. They are mostly used as wide-bandgap semiconductors or insulators.
Uses of Nitrates-
They are highly soluble and biodegradable. So, they are used as fertilizers. They are used as oxidizing agents because the quick oxidation of carbon compounds results in the liberation of gases. So, they are used in explosives.
