$Cu_{(s)} + FeSO_{4(aq)} \longrightarrow CuSO_{4(aq)} + Fe_{(s)}$

Vedclass · Answer

(D) chemical reaction is possible if a more reactive metal displaces a less reactive metal from its salt solution. According to the reactivity series of metals,the order is $Zn > Fe > Cu$.$1$. In option $A$,$Zn$ is more reactive than $Cu$,so it displaces $Cu$. This reaction is possible.$2$. In option $B$,$Zn$ is more reactive than $Fe$,so it displaces $Fe$. This reaction is possible.$3$. In option $C$,$Fe$ is more reactive than $Cu$,so it displaces $Cu$. This reaction is possible.$4$. In option $D$,$Cu$ is less reactive than $Fe$. Therefore,$Cu$ cannot displace $Fe$ from $FeSO_4$ solution. This reaction is not possible.
