Write the reaction equation: Al – AlCl3- Al (OH) 3- Al2O3- NaAlO2

According to this chain, the chemical equations will look like this:

1) 2Al + 3Cl2 → 2AlCl3
Aluminum react with chlorine to produce aluminum chloride. Aluminum powder.

2) AlCl3 + 3NaOH → Al (OH) 3 + 3NaCl
Aluminum chloride react with sodium hydroxide to produce aluminum hydroxide and sodium chloride. Sodium hydroxide – diluted solution.

3) 2Al (OH) 3 → Al2O3 + 3H2O
The thermal decomposition of aluminum hydroxide to produce aluminum oxide and water. This reaction takes place at a temperature of over 575 ° C.

4) Al2O3 + 2NaOH → 2NaAlO2 + H2O
Aluminum oxide react with sodium hydroxide to produce sodium aluminate and water. This reaction takes place at a temperature of 900-1100 ° C.
