Question

Why does the colour of copper sulphate solution fade when an iron nail is dipped in it? Explain with the help of an equation?

Answer 1

So, when an iron nail is dipped in a copper sulphate solution, iron displaces copper from its solution to form iron sulphate, which is green in color. Hence, the blue color of copper sulphate solution changes into green color because of this displacement reaction.

Answer 2

So,when an iron nail is dipped in a copper sulphate solution,iron displaces copper from its solution to form iron sulphate,which is green in color.hence,the blue color of copper sulphate solution changes into green color because of this displacement reactions.
