Suatu sel Volta ditulis dalam notasi sel berikut.

Cu(s) | Cu2+(aq) || Ag+(aq) | Ag(s)

Persamaan reaksi sel dari notasi sel tersebut adalah....

2Ag(s) + Cu2+(aq) → 2Ag+(aq) + Cu(s)

2Ag(s) + Cu(s) → 2Ag+(aq) + Cu2+(aq)

2Ag+(aq) + Cu(s) → 2Ag(s) + Cu2+(aq)

2Ag+(aq) + Cu2+(aq) → 2Ag(s) + Cu(s)

Ag+(aq) + Cu(s) → Ag(s) + Cu2+(aq)

Diketahui potensial sel untuk reaksi berikut.

Zn(s) + Fe3+(aq) → Zn2+(aq) + Fe(s)      E° = +0,32 V

Zn(s) + Ag+(aq) → Zn2+(aq) + Ag(s)      E° = +1,56 V

Fe(s) + Ag+(aq) → Fe2+(aq) + Ag(s)       E° = +0,24 V

Berdasarkan data potensial sel, dapat disimpulkan bahwa urutan ketiga logam tersebut dalam urutan reduktor yang menurun adalah....
