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

Interaction of aluminum and oxygen. As a result of the reaction, trivalent aluminum oxide is formed. The chemical equation for the reaction is as follows:

4 Al + 3 O2 = 2 Al2O3
Reaction between trivalent aluminum oxide and hydrochloric acid. As a result of the reaction, aluminum chloride is formed and water is released. The chemical equation for the reaction is as follows

Al2O3 + 6 HCl = 2 AlCl3 + 3 H2O
The interaction of aluminum chloride and sodium hydroxide, we get aluminum hydroxide and sodium chloride. The chemical equation for the reaction is as follows.

AlCl3 + 3 NaOH = Al (OH) 3 + 3 NaCl
The decomposition of aluminum hydroxide to aluminum oxide and water. The chemical equation for the reaction is as follows.

2 Al (OH) 3 = Al2O3 + 3 H2O.
