(1) MnO₂ + 4HCl --> MnCl₂ + Cl₂ + 2H₂O

(2) 2Cl₂ + 2Ba(OH)₂ --> BaCl₂ + Ba(ClO)₂ + 2H₂O

(3) 3BaCl₂ + Fe₂(SO₄)₃ --> 3BaSO₄ + 2FeCl₃

(4) FeCl₃ + Ba(OH)₂ --> BaCl₂ + Fe(OH)₃

(5) CuO + 2HCl --> CuCl₂ + H₂O

(6) CuCl₂ + 2AgNO₃ --> Cu(NO₃)₂ + 2AgCl

(7) Cu(NO₃)₂ + Fe --> Fe(NO₃)₂ + Cu

(8) Cu + 2H₂SO₄ --> CuSO₄ + SO₂ + 2H₂O

(9) CuSO₄ + BaCl₂ --> CuCl₂ + BaSO₄
