The ionic equation for the reaction between nitric acid (HNO3) and iron (Fe) is:
3H+ + Fe -> Fe3+ + 3/2H2
This equation represents the dissociation of nitric acid into H+ ions and the oxidation of iron to Fe3+ ions.
When iron hydroxide reacts with nitric acid, it forms iron nitrate and water. The balanced chemical equation for this reaction is: Fe(OH)3 + 3HNO3 → Fe(NO3)3 + 3H2O
The balanced equation for the reaction between iron oxide (Fe2O3) and nitric acid (HNO3) is: Fe2O3 + 6HNO3 → 2Fe(NO3)3 + 3H2O
When nitric acid reacts with iron, iron nitrate and hydrogen gas are formed. This reaction is represented by the chemical equation: 3HNO3 + Fe -> Fe(NO3)3 + 3H2.
Nitric acid + Iron ----> Iron(III) nitrate + Water + Nitrogen dioxide
Iron reacts with dilute nitric acid to produce nitric oxide gas, iron(II) nitrate, and water. In concentrated nitric acid, iron reacts to form iron(III) nitrate, nitrogen dioxide gas, and water. In very dilute nitric acid, the reaction between iron and nitric acid is slow and may not be easily observable due to the low concentration of nitric acid.

Iron does not react with nitric acid because nitric acid is a strong oxidizing agent that forms a protective oxide layer on the surface of iron, preventing further reaction. This oxide layer acts as a barrier, blocking the acid from reaching the iron underneath, thereby preventing the reaction to occur.
When you add iron filings to nitric acid, you will observe a chemical reaction where the iron reacts with the nitric acid to produce iron nitrate and release nitrogen dioxide gas. It's a redox reaction in which the iron is oxidized and the nitric acid is reduced.
Iron forms a protective oxide layer on its surface when exposed to air, which prevents further reaction with concentrated nitric acid. The oxide layer acts as a barrier, preventing the acid from coming into contact with the underlying iron metal, thereby making iron passive towards concentrated nitric acid.
When nitric acid reacts with iron, it produces nitric oxide gas, iron(II) nitrate, and water. The reaction is exothermic and may produce heat or gas. It is important to perform this reaction in a well-ventilated area because nitric oxide gas can be toxic.
Iron reacts with concentrated nitric acid to form iron(III) nitrate, nitrogen dioxide gas, and water. This reaction is often vigorous and exothermic, producing a reddish-brown gas (NO2) due to the oxidation of nitrogen in the nitric acid.
