Reaksi yang terjadi pada sel tersebut adalah....
E° Ag = +0,80 V E° Zn = -0,76 V
Zn(s) + 2Ag+(aq) → Zn2+(aq) + 2Ag(s) E°sel = +1,56 V
2Ag+(aq) + Zn(s) → 2Ag(s) + Zn2+(aq) E°sel = +2,36 V
Zn2+(aq) + 2Ag(s) → Zn(s) + 2Ag+(aq) E°sel = +0,04 V
Zn2+(aq) + 2Ag(s) → Zn(s) + 2Ag+(aq) E°sel = +1,56 V
Zn(s) + 2Ag(s) → Zn2+(aq) + 2Ag+(aq) E°sel = +1,56 V
