铝三角化学离子方程式

氯化铝和氢氧化钠：
氢氧化钠少量：3OH- +Al3+ ==Al（OH）3↓ 过量：4OH- + Al3+ ==AlO2- + 2H2O
偏铝酸钠和盐酸：
盐酸少量：AlO2+H++H2O=Al(OH)3↓ 过量：AlO2+4H+=Al3++2H2O铝三角
(1) 2Al + 2NaOH + 2H2O === 2NaAlO2 + 3H2O
(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

1 + 3 = (s)
2 + 3 = + 3
3 + = + 2
4 + + = (s沉淀)
5 + 4 = + 2
6 + 4 = + 2
这样行么？或者你要图片？

Al3+
1 /2 5\ 6
Al(OH)3 3—4 AlO2-
1 Al3+ + 3OH- = Al(OH)3 (s)
2 Al(OH)3 + 3H+ = Al3+ + 3H2O
3 Al(OH)3 + OH- = AlO2- + 2H2O
4 AlO2- + H+ + H2O = Al(OH)3 (s)
5 Al3+ + 4OH- = AlO2- + 2H2O
6 AlO2-+ 4H+ = Al3+ + 2H2O
