Write the equations of all reactions: aluminum → aluminum chloride → aluminum hydroxide → aluminum oxide → sodium metaaluminate → aluminum sulfate.
1.2Al + 6HCl = 2AlCl3 + 3H2 ↑.
2. AlCl3 + 3NaOH = Al (OH) 3 ↓ + 3NaCl.
3.2Al (OH) 3 (at temperature) = Al2O3 + 3H2O.
4. Al2O3 + 2NaOH = 2NaAlO2 + H2O.
5.2NaAlO2 + 4H2SO4 = Na2SO4 + Al2 (SO4) 3 + 2H2O.
