Question

Least acidic and most acidic oxides of nitrogen are

Answer 1

Nitrogen form at least three acidic oxides .They are Dinitrogen trioxide,Nitrogen dioxide,Nitrogen Pentoxide. Dinitrogen is dissolved in water to form this unstable acid.

Answer 2

Answer:

Least acidic oxides of nitrogen are:

1. Nitrous oxide (N₂O)
2. Nitric Oxide (NO)
3. Dinitrogen trioxide (N₂O₃)
4. Dinitrogen tetraoxide (N₂O₄)

Most acidic oxide of nitrogen:

1. Dinitrogen pentoxide (N₂0₅)

Explanation:

• The acidic nature of the oxides of nitrogen are determined by the strength of the acid formed by nitrogen oxide in water.
• Nitrogen reacts with oxygen to form nitrogen oxide.
• The oxidation states vary from +1 to +5.
• The nitrogen with higher oxidation state among the various nitrogen oxides are most acidic than that in lower oxidation state.

The oxidation number of various oxides of nitrogen:

• N₂O : +1
• NO : +2
• N₂O₃ : +3
• N₂O₄ : +4
• N₂O₅ : +5

Note:

As the oxidation state increases, the acidic nature of the oxide also increases. Therefore, the order of acidic strength is:

N₂O ≤ NO ≤ N₂O₃ ≤ N₂O₄ ≤ N₂O₅
