Question

When iron nail is dipped in copper suphate solution ,the blue colour of copper sulphate changes to green . Explain the reason with the help of a chemical equation.

Answer 1

Step-by-step explanation:

In this case, iron, being more reactive than copper, will displace it from the solution. That is, ferrous ions or Fe(II) will go into the solution, while Cu(II) will be deposited onto the nail. This cause the solution color to change from blue to green.
