Question

Ravinder placed the iron nail in the blue solution of copper sulphate. Can you tell what will the change in the blue solution of copper sulphate?​

Answer 1

Answer:

it will change into green solutions because

Fe + CuSO4 =Fe2(SO4) + Cu

Answer 2

Answer:

The blue colour of copper sulphate solution will fade.

Explanation:

Iron is more reactive than copper.So when an iron nail is dipped in a copper sulphate solution,iron displaces copper from its solution to form iron sulphate.

Fe(s)+CuSO4(aq)--------> FeSO4(aq) +Cu(s)

Hence the blue colour of copper sulphate solution fades because of this displacement reaction.
