Answer 2

Green colour forms due to formation of ferrous sulphate.

• The reaction between copper sulphate and iron displaces copper from the solution to form ferrous sulphate.
• The reaction is single displacement reaction.
• The blue colour of copper sulphate changes to green colour of ferrous sulphate.
• The chemical reaction representing above change is - Fe(s) + CuSO4(aq) --> FeSO4(aq) + Cu(s)
• Here, Fe is oxidised to FeSO4 and Cu ions are reduced to Cu.
