To carry out the above chain of transformations, it is necessary to carry out the following reactions:

Iron react with hydrochloric acid. As a result of the reaction, ferric chloride is formed and hydrogen is released.

Fe + 2 HCl = FeCl2 + H2,
Iron chloride react with sodium hydroxide. As a result of the reaction, iron hydroxide and sodium chloride are formed.

FeCl2 + 2 NaOH = Fe (OH) 2 + 2 NaCl,
Iron hydroxide react with the addition of water and oxygen. As a result of the reaction, ferric hydroxide is formed.

4 Fe (OH) 2 + 2 H2O + O2 = 4 Fe (OH) 3,
The decomposition of ferric hydroxide.

The reaction produces iron oxide and water.

2 Fe (OH) 3 = Fe2O3 + 3 H2O.
Iron oxide reacts with carbon monoxide, resulting in the formation of pure iron and carbon dioxide.

Fe2O3 + 3 CO = 2 Fe +3 CO2
