AluminumSulfateBariumChlorideReaction
The reaction between aluminum sulfuric acid and barium chloride is a wonderful chemical change. Now there are aluminum sulfuric acid ($Al_2 (SO_4) _3 $) combined with barium chloride ($BaCl_2 $), the change is as follows:
$Al_2 (SO_4) _3 + 3BaCl_2\ longrightarrow 2AlCl_3 + 3BaSO_4\ downarrow $
Looking at this reaction, the sulfate group ($SO_4 ^ {2 -} $) in aluminum sulfuric acid and the barium ion ($Ba ^ {2 +} $) in barium chloride are combined to form a precipitation of barium sulfate ($BaSO_4 $). And aluminum ions ($Al ^ {3 +} $) and chloride ions ($Cl ^ - $) are also combined to form aluminum chloride ($AlCl_3 $). Barium sulfate is white and insoluble in water, so it looks like precipitation.
The reason for this reaction lies in the recombination of ions. Ions in solution, each according to its own nature, find their compatibility. This is the common way of chemical change, and it is also the way for us to explore the change of matter.
