Which of the following pairs will give displacement reactions?

A

NaCl solution and copper metal

B

`MgCl_(2)` solution and aluminium metal

C

`FeSO_(4)` solution and silver metal

D

`CuSO_(4)` solution and zinc metal

Text Solution

Verified by Experts

The correct Answer is:
D
Copper is less reactive than sodium, hence, no reaction will take place. Aluminium is less reactive than iron, hence, no reaction takes place. As zinc is more reactive than copper, thus, displacement reaction takes place.
