1、碱性氧化物+酸盐+H2O

Fe2O3+6HCl==2FeCl3+3H2O Fe2O3+3H2SO4==Fe2(SO4)3+3H2O

CuO+H2SO4==CuSO4+H2O ZnO+2HNO3==Zn(NO3)3+H2O

2、碱+酸盐+H2O

Cu(OH)2+2HCl==CuCl2+2H2O Cu(OH)2+H2SO4==CuSO4+2H2O

NaOH+HCl==NaCl+H2O 2NaOH+H2SO4==Na2SO4+2H2O

NaOH+HNO3==NaNO3+H2O Mg(OH)2+2HNO3==Mg(NO3)2+2H2O

Ba(OH)2+H2SO4==BaSO4+2H2O

3、酸+盐新盐+新酸

HCl+AgNO3==AgCl+HNO3 H2SO4+BaCl2==BaSO4+2HCl

Ba(NO3)2+H2SO4==BaSO4+2HNO3 NaHCO3+HCl==NaCl+H2O+CO2

4、盐1+盐2新盐1+新盐2

KCl+AgNO3==AgCl+KNO3 NaCl+AgNO3==AgCl+NaNO3

Na2SO4+BaCl2==BaSO4+2NaCl BaCl2+2AgNO3==2AgCl+Ba(NO3)2

5、盐+碱新盐+新碱

CuSO4+2NaOH==Cu(OH)2+Na2SO4 FeCl3+3NaOH==Fe(OH)3+3NaCl

Ca(OH)2+Na2CO3==CaCO3+2NaOH NaOH+NH4Cl==NaCl+NH3+H2O
