(a) Fe(OH)2

(b) Fe(OH)3

(c) FeO

(d) Fe3O4

Iron reacts with steam to form Fe3O4. Ferrosoferric oxide and hydrogen gas are produced when iron reacts with steam.

Reaction of Iron with Steam

  • 3 Fe(s) + 4 H2O(g) > 4 H2 (g) + Fe3O4 is the balanced equation.
  • This chemical reaction allows us to gather hydrogen gas.
  • Uses of Hydrogen gas:
    • Hydrogenation of oils and fats
    • Filling balloons
    • Reduction of metallic ores
    • Rocket fuel
  • Fe(OH)2 – Ferrous Hydroxide
  • FeO- Ferrous Oxide
  • Fe(OH)3 – Ferric Hydroxide


Iron reacts with steam to form (a) Fe(OH)2 (b) Fe(OH)3 (c) FeO (d) Fe3O4

Fe3O4 is formed by the reaction of iron with steam. Hydrogen gas and ferrosoferric oxide are formed by the interaction of steam and iron. The chemical reaction is as follows 3Fe (s)+4H2O (g)→Fe3O4(s)+4H2(g).
