Which of the following is true in the case of Zn-Cu cell? 

1. ​The flow of electrons takes place from copper to zinc 
2. E0 red of copper electrode is less than that of zinc electrode     
3. Zinc acts as an anode and copper as cathode 
4. All are correct

Dear Student,

Zn-Cu cell construction is of galvanic where zinc acts as anode and copper as cathode with less redox potential than zinc electrode as flow of electron takes place from copper to zinc and the flow sketch is schematically shown below,


Answer is Option(4) all are correct.

Regards.
