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
