can we store cuso4 solution in an iron vessel??
Copper sulphate solution cannot be stored in an iron vessel. This is because iron is more reactive than copper, and so is placed above copper in the reactivity series of metals. Thus, iron will displace copper from its salt and instead form ferrous sulphate. The copper metal will be deposited as a reddish brown residue. Following is the chemical equation for the reaction
Fe (s) + CuSO4 (aq) → FeSO4 (aq) + Cu (s)
