Question
Zn rod is immersed in CuSO4 solution. What will you observe after an hour? Explain your observation in terms of redox reaction.
✓
Answer
The blue colour of CusO4 solution will get discharged and reddish brown copper metal will be deposited on Zn rod. This is because blue colour Cu2+ (in CuSO4) gets reduced to Cu by accepting two electrons from Zn, which gets oxidised to colourless ZnSO4.
