2Na+2H2O=2NaOH+H22NaHCO3===(加热）Na2CO3+H2O+CO22Na2O2+2H2O==4NaOH+O2Na2O+H2O==2NaOH2Na+O2==Na2O2
2NaOH+H2SO4=Na2SO4+H2O
NaOH+HCl=H2O+NaCl
Na2CO3+2HCl=H2O+2NaCl+CO2
Na2CO3+Ca(OH)2=CaCO3沉淀+2NaOH
Na2CO3+Mg(OH)2=2NaOH+MgCO3
2NaOH+H2SO4=Na2SO4+H2O
NaOH+HCl=H2O+NaCl
Na2CO3+2HCl=H2O+2NaCl+CO2
Na2CO3+Ca(OH)2=CaCO3沉淀+2NaOH
Na2CO3+Mg(OH)2=2NaOH+MgCO3
