The chemical equation above describes the reaction between iron(III) oxide (Fe2O3) and nitric acid (HNO3) to form iron(III) nitrate (Fe(NO3)3) and water (H2O).
-
Reaction conditions: The reaction occurs in an acidic environment and at room temperature.
-
Reaction process: When Fe2O3 reacts with HNO3, the products obtained are Fe(NO3)3 and H2O. If water is further added, Fe(NO3)3 will dissolve, forming a brown-yellow solution.
-
Occurring phenomena: When Fe2O3 reacts with HNO3, the reaction occurs along with the release of nitrogen dioxide (NO2), which pollutes the surrounding environment. The product obtained is Fe(NO3)3, a brown-yellow solid that is soluble in water.
