Give reasons for the following:
Blue colour of copper sulphate solution is destroyed when iron fillings are added to it.

Academic Chemistry NCERT Class 10

The blue colour of copper sulphate is destroyed because iron displaces copper from copper sulphate solution as it is more reactive than copper.
