1. Electrolysis of aluminum oxide at 900 ° C.
2Аl2O3 = 4Al + 3O2.
2. The exchange reaction with the formation of aluminum chloride:
Al + FeCl3 = AlCl3.
3. Under the action of alkali on salt, a precipitate is formed in the form of hydroxide:
AlCl3 + 3NaOH = Al (OH) 3 + 3NaCl.
4. Decomposition of aluminum hydroxide at high temperature:
Al (OH) 3 = Al2O3 + 3H2O.
