1. When iron is oxidized, iron (III) oxide is formed.

4Fe + 3O2 = 2Fe2O3.

2. Iron oxide when heated is capable of reacting with water to form iron (III) hydroxide.

Fe2O3 + 3H2O = 2Fe (OH) 3.

3. Iron (III) hydroxide, reacting with sulfuric acid, forms iron (III) sulfate.

2Fe (OH) 3 + 3H2SO4 = Fe2 (SO4) 3 + 3H2O.
