The following galvanic cell was `Zn|{:(Zn(NO_(3))_(2(aq.))),(100 mL"," 1M):}||{:(Cu(NO_(3))_(2(aq.))),(100 mL"," 1M):}|Cu` operated as ann electrolytic cell using `Cu` as anode `Zn` as cathode. A current of `0.48` ampere was passed for `10` hour and then the cell was allowed to funcation as galvanic cell. What would be the `e.m.f.` of the cell at `25^(@)C`? Assume that the only electrode reactions occuring were those involving `Cu//Cu^(2+)` and `Zn//Zn^(2+)`. (Given `E_(Cu^(3+)//Cu)^(@) = + 0.34 V` and `E_(Zn^(2+)//Zn)^(@) = -0.76 V`) |
