铝三角 那一对反应

1 AlCl3 + 3NH3·H2O=Al(OH)3↓+3NH4Cl
2 Al(OH)3 + 3HCl==AlCl3 + 3H2O
3 NaAlO2+HCl+H2O=NaCl+Al(OH)3↓
或者CO2+2NaAlO2+3H2O=2Al(OH)3↓+Na2CO3
4 Al(OH)3 + NaOH==NaAlO2 + 2H2O
5 AlCl3+4NaOH == NaAlO2+3NaCl+2H2O
6 NaAlO2+4HCl==AlCl3+2H2O

2AL+2NaOH+2H20=2NaALO2+3H2
2AL+6H+ =2AL3+ +3H2
AL3+ +3OH- =AL(OH)3
Al(OH)3 + 3H+ = Al3+ + 3H2O
AL(OH)3+OH- =ALO2- +2H2O
3ALO2-+ AL3+ + 6H2O=4AL(OH)3
ALO2- +4H+ =AL3+ +2H2O

2AL+2NaOH+2H20====2NaALO2+3H2
3ALO2-+ AL3+ + 6H2O====4AL(OH)3
Al(OH)3 + 3H+ ==== Al3+ + 3H2O
2AL+6H+ =2AL3+ +3H2
AL(OH)3+OH- =ALO2- +2H2O
