State the reason and write chemical equation of the reaction. 2014 Answer A strip of zinc metal is put in copper sulphate solution. The blue colour of copper sulphate solution fades gradually due to the formation of colourless zinc sulphate solution. Since zinc is more reactive than copper, zinc displaces copper from copper sulphate solution.
