Detailed information about the equation Fe + 3HNO3 -> Fe(NO3)3 + 3NO2 + 3H2O
- This equation describes the reaction process between iron (Fe) and nitric acid (HNO3) to produce iron (III) nitrate (Fe(NO3)3), nitrogen dioxide (NO2) and water (H2O).
- According to the coefficients of the equation, we can see that each mole of iron will react with 3 moles of nitric acid to produce 1 mole of iron (III) nitrate, 3 moles of nitrogen dioxide and 3 moles of water.

Reaction conditions
- The reaction occurs under room temperature conditions.
- Iron needs to be stainless or highly pure iron to ensure the reaction is effective.
-
Reaction process
- Iron reacts with nitric acid to produce iron (III) nitrate, nitrogen dioxide and water.
- This is an oxidation-reduction reaction. Iron is oxidized from an oxidation state of 0 to an oxidation state of +3, while nitrogen in HNO3 is reduced from an oxidation state of +5 to an oxidation state of +4.
