Аразсультан · Answer 1

2Al + 3H2SO4 = Al2 (SO4) 3 + 3H2

Al2 (SO4) 3 + 3BaCl2 = 3 BaSO4 + 2AlCl3

AlCl3 + 3NaOH = Al (OH) 3 + 3NaCl

2Al (OH) 3 - > Al2O3 + 3H2O

Al2O3 + 2NaOH = 2NaAlO2 + H2O

Андрэи · Answer 2

2Al + 2H₂SO₄ = Al₂ (SO₄) ₃ + 3H₂

Al₂ (SO₄) ₃ + 3BaCl₂ = 3BaSO₄ + 2AlCl₃

AlCl₃ + 3KOH = 3KCl + Al (OH) ₃

2Al (OH) ₃ = Al₂O₃ + 3H₂O (t_)

Al₂O₃ + 2NaOH = 2NaAlO₂ + H₂O
