Assertion: Colour of Copper Sulphate does not change when Iron nail is dipped into it.
Reason: Iron is more reactive than Copper Sulphate and it displaces it

Colour of copper sulphate does not change when iron nail is dipped into it.

✒ $\bf\gray{Assertion\:is\:\underline{wrong}}.$

☆ When an iron nail immersed in the solution of copper sulphate then iron displaces copper from the solution of copper sulphate because iron is more reactive than copper.

✔ Therefore copper sulphate solution colour changes from blue to pale green.

$\Large\bf{\color{lime}ReAsOn;-}$

Iron is more reactive than copper sulphate and it displaces it.

✒ $\bf\pink{Reason\:is\:\underline{correct }}.$

☆ We know that Iron is placed above copper in the activity series. Thus iron is more reactive than copper.

✔ Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal.
