Question

Which of the metal is unable to discharge the blue colour from cuso4?

Answer 1

I do not Know If There Is Any Metal That can Discharge It But I know A Different Method -

Heat Blue CuSO4 (Blue Due to H2O). It will Lose It's Blue Colour due to the loss of H2O from Evaporation And CuSO4 Will Come back to It's Normal Form.
