WebJul 29, 2016 · Refer to the previous question: "Acids can oxidize iron since the redox potentials E for pH=0 show that H X + can oxidize iron to F e X 2 + but non-oxidizing acids (in this case HCl) cannot further oxidize F e X 2 + to F e X 3 + ." If there is presence of oxygen, it can oxidize to F e X 3 +. – Nilay Ghosh Jan 22, 2024 at 7:27 Add a comment Web2 years ago. Undiluted acids are very dangerous. Concentrated HCl or Concentrated H2SO4 will react VERY vigorously with the metal. The reaction with concentrated acids is highly exothermic (releasing heat). The H2 gas that is produced as a result of the reaction might get ignited by the heat, and burn violently. WebThe reaction between iron and nitric acid eventually produces a red-brown rust colour (iron(III) oxide). Students could link this with corrosion and acid rain.
