In water, HNO3 produces H+ ions. Which is the name for HNO3 in an aqueous solution?
2 answers:
<u>Answer:</u> It is named as nitric acid in aqueous solution.
<u>Explanation:</u>
is an acid because it releases hydrogen ions when dissolved in water. The chemical equation for the ionization of
follows:
When an element is present in the higher oxidation state in a compound, a suffix '-ic' is added at the end.
When an element is present in the lowest oxidation state in a compound, a suffix '-ous' is added at the end.
Nitrogen shows oxidation state of +5 and +3. In the given compound, nitrogen is present in +5 oxidation state. Thus, in the naming of the compound, a suffix '-ic' is added.
Hence, the given compound is named as nitric acid in aqueous solution.
