2NaHCO3===Na2CO3+H2O+CO2
Na2S2O3+H2SO4===Na2SO4+S+SO2+H2O
Na3PO4+HCl===Na2HPO4+NaCl
Na2HPO4+HCl===NaH2PO4+NaCl
NaH2PO4+HCl===H3PO4+NaCl
Na2CO3+HCl===NaHCO3+NaCl
NaHCO3+HCl===NaCl+H2O+CO2
3Na2CO3+2AlCl3+3H2O===2Al(OH)3+3CO2+6NaCl
3Na2CO3+2FeCl3+3H2O===2Fe(OH)3+3CO2+6NaCl
3NaHCO3+AlCl3===Al(OH)3+3CO2
3NaHCO3+FeCl3===Fe(OH)3+3CO2
3Na2S+Al2(SO4)3+6H2O===2Al(OH)3+3H2S
3NaAlO2+AlCl3+6H2O===4Al(OH)3
3Na2S+8HNO3(稀)===6NaNO3+2NO+3S+4H2O
3Na2SO3+2HNO3(稀)===3Na2SO4+2NO+H2O
2Na2SO3+O2===2Na2SO4
2NaOH+SO2(少量)===Na2SO3+H2O
NaOH+SO2(足量)===NaHSO3
2NaOH+SiO2===NaSiO3+H2O
2NaOH+Al2O3===2NaAlO2+H2O
2NaOH+Cl2===NaCl+NaClO+H2O
NaOH+HCl===NaCl+H2O
NaOH+H2S(足量)===NaHS+H2O
2NaOH+H2S(少量)===Na2S+2H2O
3NaOH+AlCl3===Al(OH)3+3NaCl
NaOH+Al(OH)3===NaAlO2+2H2O
(AlCl3和Al(OH)3哪个酸性强?)
NaOH+NH4Cl===NaCl+NH3+H2O
H2SO4(浓)+NaCl===NaHSO4+HCl
H2SO4(浓) +2NaCl===Na2SO4+2HCl
H2SO4(浓)+NaNO3===NaHSO4+HNO3
Na2O+SO3===Na2SO4
Na2O+CO2===Na2CO3
Na2O+2HCl===2NaCl+H2O
2Na2O2+2CO2===2Na2CO3+O2
Na2O2+H2SO4(冷,稀)===Na2SO4+H2O2
Na2O+H2O===2NaOH
2Na2O2+2H2O===4NaOH+O2
CO2+2NaOH(过量)===Na2CO3+H2O
CO2(过量)+NaOH===NaHCO3
NH3+NaCl+H2O+CO2===NaHCO3+NH4Cl
(此反应用于工业制备小苏打,苏打)
2NH3+2Na==2NaNH2+H2
(NaNH2+H2O===NaOH+NH3)
2NH3+2Na==2NaNH2+H2
(NaNH2+H2O===NaOH+NH3)
Cl2+2NaOH===NaCl+NaClO+H2O
