Write the reaction equation: AI2 (SO4) 3- AICI3- AI (OH) 3

In order to carry out the chain of transformations indicated in the task in chemical reactions, it is necessary to carry out two reactions.

The first is the interaction of a salt of trivalent aluminum sulfate with a salt of sodium chloride. The aluminum chloride salt and sodium sulfate salt we need for the next reaction are formed. The molecular equation of the reaction can be written as follows:

Al2 (SO4) 3 + 6 NaCl = 2 AlCl3 + 3 Na2SO4
The second reaction takes place with aluminum chloride and potassium hydroxide. Formed aluminum hydroxide and potassium chloride salt. The homology chain has been passed. Graphically, this equation of a chemical reaction can be expressed as follows:

AlCl3 + 3 KOH = Al (OH) 3 + 3 KCl.
