The blue colour of cuso4 slowly dissapperss when zinc rod is dipped in

Answer»

The FOLLOWING chemical reaction takes place:


Zn + CuSO₄ ---------> ZnSO₄ + Cu


The BLUE colour of the solution is due to the presence of Copper sulphate (CuSO₄);

As the reaction proceeds the Copper from CuSO₄ is slowly displaced by Zinc THUS forming ZnSO₄ which is COLOURLESS, so the blue colour disappears slowly and a colourless solution starts forming.


Hope it helps!!
