Iron + Nitric acid ----> Iron(III) nitrate + Water + Nitrogen Dioxide
Fe + HNO3 ----> Fe(NO3)3 + H2O + NO2
NOTE: Nitrogen dioxide will come out only if the acid is concentrated. If it is dilute, Nitrogen monoxide will be produced.

It depends on concentrations. Normally it emits H2.
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. Iron nitrate is a soluble salt, while water is a byproduct of the reaction.
1-diluted : Fe+4HNo3ـــــــــــــــdilu. + heatــــــــــــ Fe(No3)3+2H2o+No 2-with concentrated no reaction occurs becase of the iron passivity which is due to the oxidizing property of the acid were a layer of the metal oxide is formed which is complete and non porous so it protects the metal from further reaction
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 nitric acid and iron react together Iron Nitrate is formed and hydrogen gas
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 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.
HNO3
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.
Products of Iron (Fe) reacting with Nitric Acid(HNO3) depends on temperature of reactants as well as concentration of HNO3. With dilute HNO3 Iron gives Ferrous Nitrate [Fe(NO3)2], water and Nitric oxide(NO). 3Fe + 8HNO3 --> 3Fe(NO3)2 + 4H2O + 2NO With concentrated HNO3 iron gives Ferric nitrate [Fe(NO3)3], water and Nitrogen dioxide(NO2). Fe + 6HNO3 --> Fe(NO3)3 +3H2O + 3NO2 Reaction of iron with concentrated Nitric acid Renders it passive to further reaction due to formation of thin oxide layer on the surface. In all these Reactions Nitric acid acts as an oxidising agent.
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.
