Question

when iron is added to cuso4 solution copper is precipitated

Answer 1

when Fe is added to CuSO4 solution, Fe being more reactive than Cu ,displaces Cu.
Fe + CuSO4 ------> FeSO4 +Cu (ppt.)

Answer 2

when iron is added to $CuSO_4$ solution copper is precipitated due to the formation of copper by single displacement reaction.

Explanation:

• In the given case, the reactants are Iron (Fe) and copper sulfate solution ($CuSO_4$).
• As iron is more reactive than copper, it displaces the copper from copper sulfate solution and forms ferrous sulfate and copper as the product.
• The reason for precipitation of copper is due to single displacement reaction because of the difference in reactivity.
• The chemical equation involved in the reaction as follows:

$2Fe+CuSO_4\rightarrow Fe_2SO_4+Cu$
