Question

why does the colour of copper sulphate solution change when an iron nail is dipped in it

guys please short answer​

The nail gradually dissolves. The blue colour of copper sulphate solution gradually fades and red colored copper metal is deposited on iron nail.

When an iron nail is added to copper sulphate solution, iron atom loses two electrons and is converted to ferrous ion (Fe²+).Thus iron undergoes oxidation . On the other hand, cupric ion (Cu²+) gains two electrons to be converted to copper atom (Cu).The copper undergoes reduction.
