Write the reaction equation: Al2 (So4) 3 – AlCl3 – Al (OH) 3

To carry out the above chain of transformations, we need to carry out two reactions.

Trivalent aluminum sulfate react with barium chloride salt. As a result of the reaction, molar aluminum chloride and barium sulfate are formed. The chemical equation for the reaction is as follows:

Al2 (SO4) 3 + 3 BaCl2 = 2 AlCl3 + 3 BaSO4
The second reaction is the interaction of aluminum chloride and sodium hydroxide, as a result of the reaction, aluminum hydroxide and sodium chloride are formed.

AlCl3 + 3 NaOH = Al (OH) 3 + 3 NaCl.
