1. 4AL+ 3O₂ = 2AL₂O₃
2. AL₂O₃ + 6HCL = 2ALCL₃ + 3H₂O
3. ALCl₃ + 3NaOH = AL(OH)₃ + 3NaCL
4. AL(OH)₃ + NaOH(избыток) = Na[AL(OH)₄]
5. 2AL(OH)₃ + 3H₂SO₄ =AL₂(SO₄)₃ + 6H₂O
6. 2Na[Al(OH)₄] + 4H₂SO₄ = Na₂SO₄ + AL₂(SO₄)₃ + 4H₂O
7. AL₂O₃ + 2NaOH + 3H₂O = 2Na[AL(OH)₄]
8. 2AL + 3CL₂ = 2ALCL₃
9. AL₂O₃ + 3H₂SO₄ = AL₂(SO₄)₃ + 3H₂O
