Q59. A Daniel Cell is made at 25°C by connecting Zn / Zn+2 (0.1 M, 1 litre ) & Cu / Cu+2 (0.9 M, 1 litre ) electrode. The cell is discharged till its emf reaches 1.10 volt, then it is charged (reversing the discharge process ) by passing 0.6 F charge.
Select the incorrect option is.
(1) Concentration of Zn+2 becomes 1 M when EMF reach 1.10 volt.
(2) Concentration of Cu+2 becomes 0.5 M when EMF reach 1.10 volt.
(3) EMF of the cell just after charging is 1.118 volt
(4) After charging concentration of Cu+2 becomes 0.8 volt.
