Which metal can displace iron from iron(II) sulfate solution? MCQ with Answer and Explanation

Which metal can displace iron from iron(II) sulfate solution?
A. Mercury
B. Zinc
C. Copper
D. Silver
Answer: Option B
Solution (By JKSSB Mock Tests)
Zinc is more reactive than iron (above in the reactivity series), so it can displace iron: Zn + FeSO₄ → ZnSO₄ + Fe. Silver, copper, and mercury are less reactive than iron and cannot displace it. The reactivity series predicts displacement: a more reactive metal displaces a less reactive one.
