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.

(1) Reaction:

$$\mathrm{Fe}_{(s)} + \mathrm{CuSO}_{4(aq)} \longrightarrow \mathrm{FeSO}_{4(aq)} + \mathrm{Cu}_{(s)}$$

(2) Displacement reaction. In this reaction, a more reactive element displaces a less reactive element from its compound solution.

(3) Zinc (Zn) and Aluminium (Al).
