Ca+H2O=CA(OH)2+H2                                            
cuso4+ba(oh)2=cu(oh)2+baso4

Na₂O+H₂O=2NaOH
CaO+H₂O=Ca(OH)₂
CuSO₄+2NaOH=Cu(OH)₂+Na₂SO₄
FeCl₃+3NaOH= Fe(OH)₃+2NaCl

2Na+2H₂O=2NaOH+H₂
Na₂SO₄+Ba(OH)₂=BaSO₄+2NaOH
CuCl₂+Ca(OH)₂=Cu(OH)₂+CaCl₂
BaO+H₂O=Ba(OH)₂

CuSO₄+2KOH=Cu(OH)₂+K₂SO₄
Cu(NO₃)₂+H₂S =CuS+2HNO₃
CuSO₄+Ba(OH)₂=BaSO₄+Cu(OH)₂
Cu(NO₃)₂+Ba(OH)₂=Ba(NO₃)₂+Cu(OH)₂
