Question

Cuso4 cannot be contained in iron vessel

Answer 1

CuSO4 cant be contained in iron vessel as unfortunately iron is more reactive than copper and can easily displace the copper in the solution.....this is actually why copper sulphate is usually stored in glass containers

Answer 2

Hii..
Iron is more reactive than copper so it will displace copper from its salt and instead form ferrous sulphate. The copper metal will be deposited as a reddish brown residue

Fe (s)+CuSO4 (aq) → FeSO4 (aq) + Cu (s)

Hope it helps..!!
