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
