Write the reaction equations: aluminum – aluminum chloride – aluminum hydroxide – sodium aluminate – aluminum nitrate.
1) 2Al2O3 → 4Al + 3O2 (decomposition reaction);
2) 2Al + 6HCl → 2AlCl3 + 3H2 (substitution reaction);
3) AlCl3 + 3NaOH → 3NaCl + Al (OH) 3 ↓ (exchange reaction);
4) Al (OH) 3 ↓ + NaOH → NaAlO2 + 2H2O (exchange reaction);
5) NaAlO2 + 4HNO3 → NaNO3 + Al (NO3) 3 + 2H2O (exchange reaction).
