1) 4Al + 3O2 → 2Al2O3 (compound reaction; aluminum, oxygen, aluminum oxide);

2) Al2O3 + 6HCl → 2AlCl3 + 3H2O (exchange reaction; aluminum oxide, hydrochloric acid, aluminum chloride, water);

3) AlCl3 + 3NaOH → Al (OH) 3 ↓ + 3NaCl (exchange reaction; aluminum chloride, sodium hydroxide, aluminum hydroxide, sodium chloride);

4) 2Al (OH) 3 ↓ + 3H2SO4 → Al2 (SO4) 3 + 6H2O (exchange reaction; aluminum hydroxide, sulfuric acid, aluminum sulfate, water).
