Question

Explain the process of casting iron nails in solution of cu5ou ( including chemical eqution.​

Answer 1

Answer:

Iron nails lose their shiny appearance because an insoluble layer of copper is formed on the nails, Meanwhile, the solution,CuSO

4

loses its blue color because of the formation of FeSO

4

. This reaction is called displacement reaction in which the reactive element Iron, Fe has displaced less reactive Copper from its solution, The chemical equation can be written as:

Fe+CuSO

4

→Cu+FeSO
