Which of the following pairs cannot undergo displacement reaction?
A. iron sulphate solution and magnesium
B. zinc sulphate solution and iron
C. zinc sulphate solution and calcium
D. silver nitrate solution and copper
Answer :
Zinc sulphate solution and calcium cannot undergo displacement reaction.
This is because zinc is more reactive than iron. Hence, iron cannot displace zinc from zinc sulphate solution.
