What are the changes that can be observed with the iron rod and the colour of copper sulphate solution?

Statement 1: When a copper wire is dipped in silver nitrate solution, there is no change in the colour of the solution. Statement 2: Copper cannot displace silver from its salt solution

a) What are the changes that can be observed with the iron rod and the color of copper sulphate solution if iron rod is dipped in copper sulphate solution? b) Write the equation of the oxidation and reduction reactions. c) What will be the change if silver rod is used instead of iron rod? What is the reason?
