Question

Name the following compound: HNO3 Hydrogen nitrate Hydrogen nitrite Nitric acid Nitrous acid

Answer 1

Answer: Option (c) is the correct answer.

Explanation:

The given compound is $HNO_{3}$ and it has one hydrogen atom, one nitrogen atom and three oxygen atoms.

Name of this compound is nitric acid. Since, oxidation state of nitrogen in $HNO_{3}$ is +5 hence, a suffix "ic" is added to the name of this acid.

Whereas a compound with chemical formula $HNO_{2}$ is nitrous acid. Here, oxidation state of nitrogen atom is +3 hence, a suffix "ous" is added to the name of this acid.

Thus, we can conclude that name the compound $HNO_{3}$ is nitric acid.

Answer 2

The compound HNO3 is called nitric acid.

HNO3 is a covalent compound and  a strong acid which ionizes in water into H+ (proton) and NO3- (nitrate ion).

HNO3 (aq) ↔ H+(aq) + NO3-(aq)

Ans: HNO3 = Nitric Acid

[On a side note: Nitrous acid is HNO2]
