$$\begin{gathered} \mathit{Q}\mathbf{.}\mathbf{33} Give the reaction if any when the following metals are tested with copper sulphate solution. \\ \left(i\right) Pt \\ \left(ii\right) Zn \\ \left(iii\right) Ag \end{gathered}$$

Dear Student,

Please find below the solutions of your asked query:

(i) As Platinum(Pt) is less reactive than Copper(Cu), so it will not be able to displace Copper from Copper Sulphate solution(CuSO₄). Thus, no reaction takes place in this case.

(ii) As Zinc(Zn) is more reactive than Copper(Cu), so it will displace Copper from Copper Sulphate solution(CuSO₄). Thus, displacement reaction takes place in this case which leads to the formation of Zinc Sulphate solution(ZnSO₄) & Copper(Cu).

Reaction Involved:

Zn_(s) + CuSO_4(aq) $\stackrel{\mathbf{Displacement}\mathbf{ }\mathbf{Reaction}}{\mathbf{\to }}$ ZnSO_4(aq) + Cu_(s)

(iii) As Silver(Ag) is less reactive than Copper(Cu), so it will not be able to displace Copper from Copper Sulphate solution(CuSO₄). Thus, no reaction takes place in this case.

Hope this information clears your doubts about the topic.

Looking forward to hear from you again!
