During the working of the Daniel cell , which of the following happen ?

Answer»

the size of the Zn rod as well as the INTENSITY of the COLOUR of `CuSO_(4)` solution remain unchanged
the size of the Zn rod is REDUCED andthe blue colour of `CuSO_(4)` solution become faint
the size of the Zn rod remains same but the blue colour of `CuSO_(4)` solution become faint
the size of the Zn rod is reduced but there is no change in the intensity of colour of the `CuSO_(4)` solution

Solution :Zn dissolves to give `Zn^(2+)` ION at anode and `Cu^(2+)` deposited at cathode.
