Question

Why does the colour of copper sulphate change when an iron nail is dipped in it ? name the reaction and give example for 0 answer?

Answer 1

Iron is more reactive than copper. 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

does copper sulphate solution colour which is blue changes when iron nail is dipped into it because iron being more reactive than copper displaces copper from its solution and forms iron sulphate due to which the colour change it is displacement reaction
