Помогите с цепочкой Al→AlCl3→Al(OH)3→Al2O3→Al2(SO4)3→Al(OH)3→AlCl3

Answer 1

2Al + 3Cl2 = 2AlCl3
AlCl3 + 3LiOH = Al(OH)3↓ + 3LiCl
2Al(OH)3 =t°=> Al2O3 + 3H2O
Al2O3 +3H2SO4 = Al2(SO4)3 + 3H2O
Al2(SO4)3 + 6KOH = 2Al(OH)3↓ + 3K2SO4
Al(OH)3 + 3HCl = AlCl3 + 3H2O

Answer 2

2Al + 6HCl -> 2AlCl3 + 3H2
AlCl3 + 3NaOH -> Al(OH)3 + 3NaCl
2Al(OH)3 -> Al2O3 + 3H2O
Al2O3 +3 H2SO4 -> Al2(SO4)3 + 3H2O
Al2(SO4)3 + 6NaOH -> 2Al(OH)3 + 3Na2SO4
Al(OH)3 + 3HCl -> AlCl3 + 3H2O
