1) 2 Al + 6 HCl = 2 AlCl3 + 3 H2 (aluminum chloride, substitution reaction).
2) AlCl3 + 3NaOH = Al (OH) 3 + 3 NaCl (aluminum hydroxide, exchange reaction).
3) 2 Al (OH) 3 + 3 H2SO4 = Al2 (SO4) 3 + 6 H2O (aluminum sulfate, exchange reaction).
4) Al2 (SO4) 3 + 6 NaOH = 3 Na2SO4 + 2 Al (OH) 3 (aluminum hydroxide, exchange reaction).
5) 2 Al (OH) 3 = Al2O3 + 3 H2O (aluminum oxide, decomposition reaction)
6) Al2O3 + 3 Mg = 3 MgO + 2 Al (substitution reaction).
