Na₂SO₃ + 2HNO₃(конц) = Na₂SO₄ + 2NO₂ + H₂O
H₃PO₄ + 3KOH= K₃PO₄ + 3H₂O
Fe + 2HCl= FeCl₂ + H₂
Zn(OH)2 + BaO= BaZnO₂ + H₂O
Fe2O3 + 6HCl= 2FeCl₃ + 3H₂O
Cu+HCl ≠
2Cu(OH)₂ +CO₂= (СuOH)₂CO₃ + H₂O
2HCl + Na₂CO3= 2NaCl + CO₂
CuSO4 --->Cu(OH)2 --->CuO --> CuCl2
CuSO₄ + 2KOH ---> Cu(OH)₂ + K₂SO₄
Cu(OH)₂ = CuO + H₂O
CuO + 2HCl = CuCl₂ + H₂O
Fe2O3 --->Fe2(SO4)3 --->Fe(OH)3 --->FeCl3 
Fe₂O₃ + 3H₂SO₄ = Fe₂(SO₄)₃ + 3H₂O
Fe₂(SO₄)₃ + 6KOH = 2Fe(OH)₃ + 3K₂SO₄
Fe(OH)₃ + 3KCl = FeCl₃ + 3KOH
