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.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
