_______ cannot replace zinc from zinc sulphate.

Reactivity series: The reactivity series is the arrangement of metals in the decreasing order of their reactivity.

• Any metal which is placed below Zinc(Zn) in the reactivity series of metal cannot replace Zinc from Zinc sulphate(ZnSO₄) solution.
• Silver metal is placed below Zinc in the reactivity series.
• Hence, Silver(Ag) can not displace the Zinc from Zinc sulphate.

Therefore, Silver cannot replace zinc from zinc sulphate.
