Question

what happened when
(b) Iron nails are placed in copper sulphate solution?

Write word equations of the reactions involved.​

Answer 1

Answer:

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+CuSO4→Cu+FeSO4.

Answer 2

Answer:

Explanation:

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

​  

  loses its blue color because of the formation of FeSO

​  

. 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

​  

→Cu+FeSO
