5. Preparation of iron(II) sulphate (FeS04-7H20) (green vitriol) from iron: A similar
procedure as described for the preparation of white vitriol (ZnS04-7H20) is
followed. Iron(II) sulphate is prepared by the action of dil. H2S04 on iron filings.

Ans. (i) The most reactive metal is B as it can displace iron from iron (II) sulphate,
unlike A, C and D. (ii) If metal B is added to copper (II) sulphate solution, it will
displace copper from the solution. Metal B is able to displace iron, so it can also ...
