MCQ

Assertion : Copper sulphate solution is not stored in zinc vessel.

Reason : Zinc forms complex with $CuSO_4$

A
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
✓
If the Assertion is correct but Reason is incorrect.
D
If both the Assertion and Reason are incorrect.

✓

Answer

Correct option: C.

If the Assertion is correct but Reason is incorrect.

c
Copper sulphate solution is not stored in zinc vessel as $Zn$ is more reactive than copper and has tendency to replace $Cu$ from its aqueous solution.

$Zn(s) + CuSO_4(aq) \to ZnSO_4(aq) + Cu(s)$

$ZN$ cannot form complex with $CuSO_4$ although $[Zn(H_2O)_4]SO_4$ exists in aqueous $ZnSO_4$ solution. Hence assertion is true but reason is false.
