Question

如题所述

Answer 1

(1) 2Al + 2NaOH + 2H2O === 2NaAlO2 + 3H2
(2) 4Al + 3O2 === 2Al2O3(条件:点燃)
[2Al + Fe2O3 === Al2O3 + 2Fe(条件:高温)]
(3) 2Al2O3 === 4Al + 3O2↑(条件:电解)
(4) 2Al + 3Cl2 === 2AlCl3(条件:点燃)
[2Al + 6HCl === 2AlCl3 + 3H2↑]
(5) Al2O3 + 2NaOH === 2NaAlO2 + H2O
(6) Al2O3 + 6HCl === 2AlCl3 + 3H2O
(7) NaAlO2 + HCl + H2O === NaCl + Al(OH)3 ↓
(8) Al(OH)3 + NaOH === NaAlO2 + 2H2O
(9) 2Al(OH)3 === Al2O3 + 3H2O(条件:加热)
(10)Al(OH)3 + 3HCl === AlCl3 + 3H2O
(11)AlCl3 + 3NH3.H2O === Al(OH)3 ↓+ 3NH4Cl
[AlCl3 + 3NaOH === Al(OH)3 ↓ + 3NaCl]
(12) NaAlO2 + 4HCl(过) === AlCl3 + NaCl + 2H2O
(13)AlCl3+ 3 NaAlO2+ 6 H2O====4 Al(OH)3↓+3NaCl
(14)Al2(SO4)3+ 6 NaHCO3==== 2 Al(OH)3↓+ 3 Na2SO4+ 6 CO2↑
(15)2NaAlO2+ CO2(少量)+ 3 H2O ==== 2 Al(OH)3↓+ Na2CO3
(16)NaAlO2+ CO2(过量)+ 2H2O ==== Al(OH)3↓+ NaHCO3
Al(OH)3+3HCl=AlCl3+3H2O Al(OH)3+3H+= Al3++3H2O(与强酸溶液)
Al(OH)3+ NaOH=NaAlO2+2H2O Al(OH)3+ OH―=AlO－2+2H2O(与强碱溶液)
2KAl(SO4)2+6NH3?H2O=2 Al(OH)3↓+K2SO4+3(NH4)2SO4 Al3++3 NH3?H2O = Al(OH)3↓+3NH+ 4
2KAl(SO4)2+6NaOH=2 Al(OH)3↓+K2SO4+3Na2SO4 Al3++3OH―= Al(OH)3↓
AlCl3+3 NaOH= Al(OH)3↓+3NaCl Al3++3OH―= Al(OH)3↓(与强碱溶液)

Answer 2

2Al+3Cl2===2AlCl3
4Al+3O2===2Al2O3（钝化）
4Al(Hg)+3O2+2xH2O===2(Al2O3.xH2O)+4Hg
4Al+3MnO2===2Al2O3+3Mn
2Al+Cr2O3===Al2O3+2Cr
2Al+Fe2O3===Al2O3+2Fe
2Al+3FeO===Al2O3+3Fe
2Al+6HCl===2AlCl3+3H2
2Al+3H2SO4===Al2(SO4)3+3H2
2Al+6H2SO4(浓)===Al2(SO4)3+3SO2+6H2O
(Al,Fe在冷,浓的H2SO4,HNO3中钝化)
Al+4HNO(稀)===Al(NO3)3+NO+2H2O
2Al+2NaOH+2H2O===2NaAlO2+3H2
