Na2so4-- h2so4-- al2(so4)3-- al(oh)3-- al2o3 - вопрос №24242433233731579 от gazizullinnafi 05.10.2020 05:52

Question

Химия: Na2so4-- h2so4-- al2(so4)3-- al(oh)3-- al2o3

gazizullinnafi · Answer

1. 3Na₂SO₄ + Na₂S + 8СО = 4Na₂CO₃ + 4СO₂ + 4S
S +O₂=SO₂
2SO₂ +3 O₂= 2SO₃
SO₃ + H₂O=H₂SO₄
2. 3H₂SO₄ +2AI(OH)₃=AI₂(SO₄)₃ + 6H₂O
3. Al₂(SO4)₃ + 6NaOH = 2Al(OH)₃↓ + 3Na₂SO₄
4. 2Al(OH)₃=AI₂O₃+3H₂O

Na2so4--> h2so4--> al2(so4)3--> al(oh)3--> al2o3
