Study the experimental set- up shown in the diagram and write chemical equation for the chemical reaction involved. Name and define the type of reaction. List two other metals which can be used in place of iron to show the same type of reaction with copper sulphate solution.

The diagram shows an experimental setup for a chemical reaction between iron and copper sulphate solution. The reaction involves the displacement of copper from copper sulphate solution by iron. The chemical equation for this reaction is: Fe + CuSO4 $\rightarrow$ FeSO4 + Cu. This is an example of a single displacement reaction, where iron displaces copper from copper sulphate solution. Two other metals that can be used in place of iron to show the same type of reaction with copper sulphate solution are zinc and tin.
