When aluminum metal is placed in ZnSO4 solution, a single displacement reaction takes place. In this reaction, aluminum atoms displace zinc atoms from the aqueous solution to form aluminum sulfate and zinc metal.


The chemical equation for the reaction between aluminum and ZnSO4 can be represented as follows:

Al + ZnSO4 → Zn + Al2(SO4)3


The reaction between aluminum and ZnSO4 can be explained as follows:

- Aluminum metal reacts with the aqueous solution of ZnSO4.
- The aluminum atoms displace the zinc atoms from the solution to form aluminum sulfate and zinc metal.
- The displaced zinc atoms combine with the aluminum sulfate to form zinc sulfate, which remains in the aqueous solution.
- The aluminum sulfate formed during the reaction is insoluble in water and precipitates out of the solution.
- The overall result of the reaction is the formation of zinc metal and aluminum sulfate.


The following observations can be made during the reaction between aluminum and ZnSO4:

- The aluminum metal slowly dissolves in the aqueous solution of ZnSO4.
- A white precipitate of aluminum sulfate is formed during the reaction.
- The solution becomes slightly acidic due to the formation of aluminum sulfate.


In conclusion, when aluminum metal is placed in ZnSO4 solution, a single displacement reaction takes place, resulting in the formation of aluminum sulfate and zinc metal. This reaction provides a clear demonstration of the reactivity of metals and their ability to displace other metals from their compounds.

Displacement takes place. As aluminium is more reactive than zinc(which is less reactive compared to zinc) it displaces zinc from it's salt solution! The equation for the displacement of zinc by aluminium is as follows:2 Al + ZnSO4 = Al2SO4 + Zn
