What information is conveyed by the cell rotation given below?
Cu(s) | Cu2+ (aq) (0.1 M) || Ag+ (aq) (0.2 M) | Ag(s)

Answer

In cell reaction :

Cu(s) +2Ag+(aq) ---->Cu2+(aq) +2Ag(s)

Half cell reaction
Cathode (reduction ):
2Ag+(aq) +2e- -----> 2Ag(s)

Anode (oxidation)
Cu(s) -----> Cu2+(aq) +2e-

 In overall reaction of the cell, silver electrode act as cathode and copper electrode act as anode.
