A farmer prepared 1% solution of copper sulphate using iron rod as the stirrer for preparing Bordeaux mixture. Next day he notices that the blue color almost disappeared and the iron get coated with reddish brown material.
a) What is the reddish brown material deposited on the iron rod?

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?
