Question

3. Получите хлорид алюминия известными вам способами.?​

Answer 1

1При взаимодействии соли с металлом:
Al + FeCl3 → AlCl3 + Fe
Al0+Fe3+ +3Cl-=Al3+ + 3Cl- +Fe0 ( железо нулевое)))
Al0+Fe3+ = Al3+ + Fe0

2. 3CuCl2 + 2Al → 2AlCl3 + 3Cu↓
3Сu2+ +6Cl- + 2Al0=2Al3+ +6Cl- + 3Cu0
3Сu2+ + 2Al0 = 2Al3+ + 3Cu0

3. При вз.амфотерных гидроксидов и кислот



Al(OH)3 + 3HCl → AlCl3 + 3H2O
Al(OH)3+3H+ + 3CL-=Al3+ +3Cl- +3H2O
Al(OH)3+3H+=AL3+ +3h2o

Answer 2

Obtaining Aluminum Chloride

To obtain aluminum chloride, there are several known methods. One common method involves the reaction between aluminum metal and hydrochloric acid. The balanced chemical equation for this reaction is:

2 Al(s) + 6 HCl(aq) → 2 AlCl3(aq) + 3 H2(g)

This reaction produces aluminum chloride and hydrogen gas. Another method involves the reaction between aluminum oxide and carbon in the presence of chlorine gas. The balanced chemical equation for this reaction is:

Al2O3(s) + 3 C(s) + 3 Cl2(g) → 2 AlCl3(s) + 3 CO(g)

This reaction produces aluminum chloride and carbon monoxide gas.

These are the two commonly known methods for obtaining aluminum chloride.
