1) AlCl3 + 3NaOH = 3NaCl + Al (OH) 3 – exchange reaction;
2) 2Al (OH) 3 = Al2O3 + 3H2O – decomposition reaction;
3) Al2O3 + 3H2SO4 = Al2 (SO4) 3 + 2H2O – exchange reaction;
4) Al2 (SO4) 3 + 6NaOH = 3Na2SO4 + 2Al (OH) 3 – exchange reaction;
5) Al (OH) 3 + Cl2 = AL (OH) 2Cl + HOCl – compound reaction.
