Can copper sulphate solution be stored in iron container? (A) No, because Cu is more reactive than iron (B) No, because iron is more reactive than copper, therefore reaction takes place (C) Yes, because copper is less reactive than iron (D) Yes, because copper is more reactive than copper

No, because iron is more reactive than copper, therefore reaction takes place

In CuSO4 copper metal is less reactive than iron (Fe). Hence, when copper sulphate is placed in an iron tank then displacement reaction occurs. In copper sulphate copper metal is displaced by iron and the reaction is as shown by

CuSO4 + Fe → FeSO4 + Cu

Therefore, copper sulphate cannot be stored in an iron container

So, the correct option is (B)
