Solution
When an iron nail is dipped in Copper sulphate solution a displacement reaction takes place, in which one metal displaces the other metal from its salt solution.
Word Equation : Iron + Copper sulphate → Iron sulphate + copper.
Chemical Equation: Fe+CuSO4→Cu+FeSO4
A chemical change will take place when an iron nail is immersed in CuSO4 solution.
