Question

Copper displaces which of the following metals from its salt solution: [a] ZnSO4
​ [b] FeSO4
​ [c] AgNO3
​ [d] NiSO4

Answer 1

I think it is (d)Agno3

Answer 2

The displaced metal is [c] $\bold{AgNO_3}$

Explanation:

To check the displacement of metal to their metal compound, we need to check the reactivity of metal in the metal reactivity series.

Here, Copper is more reactive than Ag therefore it will replace Ag from $AgNO_3$ whereas other metals are more reactive than Cu as they are placed above Cu in the reactivity series hence Cu cannot replace them from their solution.

Hence the answer must be option (c) $AgNO_3$.
