According to this chain, the chemical equations will look like this:

1) 2Al + 6H2SO4 → Al2 (SO4) 3 + 3SO2 + 6H2O

Aluminum react with sulfuric acid to produce aluminum sulfate, sulfur (IV) oxide and water. Sulfuric acid – concentrated solution.

2) Al2 (SO4) 3 + 6 HCl → 2 AlCl3 + 3 H2SO4

Aluminum sulfate react with hydrochloric acid to produce aluminum chloride and sulfuric acid.

3) AlCl3 + 3 NaOH → Al (OH) 3 + 3 NaCl

Aluminum chloride react with sodium hydroxide to produce aluminum hydroxide and sodium chloride.

4) 2Al (OH) 3 → Al2O3 + 3H2O

The thermal decomposition of aluminum hydroxide to produce aluminum oxide and water. This reaction takes place at a temperature of over 575 ° C.
