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?

Explanation

a) Copper is deposited on iron rod and the blue oplour of copper sul phate solution decreases.

b)`Fe rarr Fe^2+ + 2e^-`
`Cu^2+ + 2e^- rarr Cu`
c) No change occurs, Roactivity of silver is less than that of copper the reactivity series the position of siver is below to copper.
