Question

Al-Na[Al(OH)4]-AlBr3-Al(Oh)3 Al(NO3)2-Al2O3-Al
Сделать ТЭД AlBr3-Al(OH)3
Сделать ТЭД Al(Oh)3-Al(NO3)2

Answer 1

Al→Na[Al(OH)₄]→AlBr₃→Al(OH)₃→ Al(NO₃)₃→AI(OH)₃ →Al₂O₃→Al

2Al + 2NaOH + 6H₂O = Na[Al(OH)₄] + 3H₂

2Na[Al(OH)₄] + 6HBr = 2AlBr₃ + 2NaOH + 3H₂O

AlBr₃ + 3NaOH = Al(OH)₃↓ + 3NaBr

Al³⁺ + 3Br⁻ + 3Na⁺ + 3OH⁻ = Al(OH)₃↓ + 3Na⁺ + 3Br⁻

Al³⁺ + 3OH⁻ = Al(OH)₃↓

Al(OH)₃ + 3HNO₃ = Al(NO₃)₃ + 3H₂O

Al(OH)₃ + 3H⁺ + 3NO₃⁻ = Al³⁺ +3NO₃ ⁻ + 3H₂O

Al(OH)₃ + 3H⁺ = Al³⁺ + 3H₂O

Al(NO₃)₃ + 3NaOH = Al(OH)₃↓ + 3NaNO₃

2AI(OH)₃ = Al₂O₃ + 3H₂O

Al₂O₃ + 3Mg = 2Al + 3MgO
