I have understood the reactions taking place in beakers 'A' and 'B'. But I am still confused why there is no change in beakers 'C', 'D' and 'E'?

Answer»


Answer :Copper is not able to replace ZINC from zinc sulphate, therefore we are not able to see any CHANGE in beaker'C'.
SIMILARLY, no REPLACEMENT occurs in beaker 'D' and 'E'.
