Q
Chemical reactions and equations

Question:

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

Answer:

Displacement reaction is the type of reaction in which the reactive metal displaces less reactive metal in the solution. When an iron nail is dipped in copper sulphate solution, the blue colour of copper sulphate fades due to the formation of ferrous sulphate, that is a green-coloured solution.
