Write the reaction equation with which you can carry out the transformation Al2 (SO4) 3 – AlCl3 – Al (OH) 3

To carry out the above chain of transformations, it is necessary to carry out the following reactions:

Aluminum sulfate react with barium chloride, resulting in the formation of aluminum chloride and barium sulfate.

Al2 (SO4) 3 + 3 BaCl2 = 2 AlCl3 + 3 BaSO4

The reaction between aluminum chloride and water, as a result of the reaction, aluminum hydroxide and hydrochloric acid are formed.

AlCl3 + 3 H2O = Al (OH) 3 + 3 HCI.
