Question

10. Напишите ионы уровнения реакций, с помощью которых можно осуществить следующую цепочку превращений Al →Al²(So⁴)³→Al(OH)³→Al²O³→NaAlO²

Answer 1

6 Al + 3H2SO4-> Al2(SO4)3 +3H2
Al2(SO4)3+2 KOH->2Al(OH)3+K2SO4
2Al(OH)3->Al2O3+H2O
Al2O3+2Na(OH)->2NaAlO2+H2O
Я так думаю!!!!!!!!!!!

Answer 2

Ions and Equations for the Given Reaction Chain

To achieve the transformation from Al to NaAlO2, we can use the following reactions:

1. Conversion of Al to Al2(SO4)3: - Al(s) + 3H2SO4(aq) → Al2(SO4)3(aq) + 3H2(g) [[1]]

2. Conversion of Al2(SO4)3 to Al(OH)3: - Al2(SO4)3(aq) + 6NaOH(aq) → 2Al(OH)3(s) + 3Na2SO4(aq) [[2]]

3. Conversion of Al(OH)3 to Al2O3: - 2Al(OH)3(s) → Al2O3(s) + 3H2O(g) [[3]]

4. Conversion of Al2O3 to NaAlO2: - Al2O3(s) + 2NaOH(aq) + H2O(l) → 2NaAlO2(aq) + 2H2O(l) [[4]]
