Question

如题所述

Answer 1

铝三角化学方程式
(1) 2Al + 2NaOH + 2H2O === 2NaAlO2 + 3H2(上升)

(2) 4Al + 3O2 === 2Al2O3(条件:点燃)
[2Al + Fe2O3 === Al2O3 + 2Fe(条件:高温)]

(3) 2Al2O3 === 4Al + 3O2(上升)(条件:电解)

(4) 2Al + 3Cl2 === 2AlCl3(条件:点燃)
[2Al + 6HCl === 2AlCl3 + 3H2(上升)]

(5) Al2O3 + 2NaOH === 2NaAlO2 + H2O

(6) Al2O3 + 6HCl === 2AlCl3 + 3H2O

(7) NaAlO2 + HCl + H2O === NaCl + Al(OH)3(沉淀)

(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(沉淀) + 3NH4Cl
[AlCl3 + 3NaOH === Al(OH)3(沉淀) + 3NaCl]

(12)NaAlO2 + HCl(过) === AlCl3 + NaOH + H2O
离子方程式
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
