Question

Reaction between iron and copper sulphate is a displacement reaction.

• A. True
• B. False

Answer 1

The correct option is A True

• A displacement reaction is a type of chemical reaction in which a more reactive metal displaces a less reactive metal from its salt solution.
• Iron (Fe) is more reactive than Copper (Cu) on the basis of the reactivity series and will displace Copper from its salt solution i.e. Copper sulphate (CuSO₄).
• $$\begin{gathered} \mathrm{Fe}\left(\mathrm{s}\right)+{\mathrm{CuSO}}_4\left(\mathrm{aq}\right)\to {\mathrm{FeSO}}_4\left(\mathrm{aq}\right)+\mathrm{Cu}\left(\mathrm{s}\right) \\ \left(\mathrm{Iron}\right)(\mathrm{Copper}\mathrm{sulphate})(\mathrm{Iron}\mathrm{sulphate})\left(\mathrm{Copper}\right) \end{gathered}$$

Therefore, the given statement is True.
