Aluminum chloride → aluminum hydroxide → aluminum oxide → aluminum sulfate.
AlCl3 → Al (OH) 3 → Al2O3 → Al2 (SO4) 3
1) Al2 (SO4) 3 + 6NaOH → 2Al (OH) 3 ↓ + 3Na2SO4 (exchange reaction);
2) 2Al (OH) 3 ↓ → Al2O3 + 3H2O (decomposition reaction);
3) Al2O3 + 3H2SO4 → Al2 (SO4) 3 + 3H2O (exchange reaction);
