1) 2Al + 6HCl = 2AlCl3 + 3H2
2Al + 6H + 6Cl = 2Al + 6Cl + 6H
2) AlCl3 + 3NaOH = 3NaCl + Al(OH)3
Al + Cl3 + 3Na + 3OH = 3Na + 3Cl + Al(OH)3
Al + 3OH = Al(OH)3
3) 2Al(OH)3 = Al2O3 + 3H2O
2Al(OH)3 = 2Al + 3O + 3H2O
4) Al2O3 + 2NaOH + 3H2O = 2Na[Al(OH)4]
2Al + 3O + 2Na + 2OH + 3H2O = 2Na + 2Al(OH)4
2Al + 3O + 2OH + 3H2O = 2Al(OH)4
5) 2Na[Al(OH)4] + 3Na2SO4 = Al2(SO4)3 + 8NaOH
2Na + 2Al(OH)4 + 6Na + 3SO4 = 2Al + 3SO4 + 8Na + 8OH
2Al(OH)4 = 2Al + 8OH
6) Al2(SO4)3 + 6NaOH = 2Al(OH)3 + 3Na2SO4
2Al + 3SO4 + 6Na + 6OH = 2Al(OH)3 + 6Na + 3SO4
2Al + 6OH = 2Al(OH)3
7) Al(OH)3 +3HCl = 3H2O + AlCl3
Al(OH)3 + 3H + 3Cl = 3H2O + Al + 3Cl
Al(OH)3 + 3H = 3H2O + Al
8) AlCl3 + 4NaOH (избыток) = 3NaCl + Na[Al(OH)4]
Al + 3Cl + 4Na + 4OH = 3Na + 3Cl + Na + Al(OH)4
Al + 4OH = Al(OH)4
2KMnO4 +5H2O2 +3H2SO4 =K2SO4 +2MnSO4+8H2O +5O2
