Answer:

When iron nail are placed in copper sulphate solution displacement reacting takes place in which iron displace copper. The blue colour turns into green. (Some iron nails turn red in colour.)

Explanation:

Equation of reaction

Nails iron (Fe) +Copper sulphate

(CUSO4)-Iron Sulphate (FeSo4) +Copper (Cu)
