① 2Na + O2====Na2O2(淡黄色)条件为点燃
② 2Na2O2 + 2H2O = 4NaOH + O2↑ 2Na+ 2H2O = 2Na+ + 2OH- + H2↑
③ 2Na2O2 + 2H2O= 4NaOH + O2↑ 2Na2O2+ 2H2O = 4Na+ + 4OH-+ O2↑
④ 2Na2O2 + 2CO2= 2Na2CO3 + O2
⑤ 2NaCl +2 H2O ====2NaOH + H2↑ + Cl2↑(氯碱工业)
2Cl- +2 H2O ====2OH - + H2↑ + Cl2↑
⑥ Na2CO3 + H2O +CO2 = 2NaHCO3 CO3 2-+ H2O +CO2 =2HCO3-
⑦ 2NaClO + H2O +CO2 = Na2CO3+HClO
① 4Al + 3O2 ====2Al2O3 条件为点燃 2Al + Fe2O3 ==== 2Fe +Al2O3条件为高温
② 2Al + 2NaOH + 2H2O =2NaAlO2 + 3H2↑ 2Al +2OH- +2H2O= 2AlO2- +3H2↑
③ 2Al2O3 ==== 4Al+3O2↑条件为电解
④ Al2O3+6HCl = 2AlCl3+3H2O Al2O3 + 6H+= 2Al3+ + 3H2O
⑤ Al2O3 + 2NaOH =2NaAlO2 +H2O Al2O3 + 2OH- = 2AlO2- + H2O
⑥ AlCl3 +3NH3·H2O = Al(OH)3↓+ 3NH4Cl Al3+ + 3NH3·H2O = Al(OH)3↓+ 3NH4+
AlCl3 +3NaOH = Al(OH)3↓+ 3NaCl Al3+ + 3OH- = Al(OH)3↓
⑦ Al(OH)3 + NaOH =NaAlO2+2 H2O Al(OH)3 + OH- = AlO2- +2H2O
⑧ Al3+ +3 AlO2- +6H2O= 4Al(OH)3↓
