Question

осуществить превращение AL → AL2(SO4)3 → AL(OH)3 → ALCL3 → AL(NO3)​

Answer 1

Ответ:

Al + H2SO4 = Al2(SO4)3 + H2↑

Al2(SO4)3 + 6NaOH = 3 Na2SO3 +2Al(OH)3↓

Al(OH)3 + 3НCl = AlCl3 + 3H2O

2AlCl3 + 3Cu(NO3)2 = 2Al(NO3)3 + 3CuCl2↓

Answer 2

1. AL + H2SO4 → AL2(SO4)3 + H2
2. AL2(SO4)3 + 6H2O → 2Al(OH)3 + 3H2SO4
3. Al(OH)3 + 3HCl → AlCl3 + 3H2O
4. Al(OH)3 + 3HNO3 → Al(NO3)3 + 3H2O

Therefore, the complete conversion of AL to AL(NO3)3 involves the following steps:

AL → AL2(SO4)3 → Al(OH)3 → AlCl3 → Al(NO3)3
