Suatu sel volta terdiri dari elektroda Ag yang dicelupkan di adalam larutan AgNO3 1 M dan elektroda Zn yang di celupkan kedalam larutan ZnSO4 1 M, jika diketahui
Ag+ (aq) + e → Ag (s) E° = + 0,80 V
Zn2+ + 2e → Zn (s) E° = – 0,76 V
Pernyataan berikut ini benar, kecuali
Elektroda Ag sebagai katoda
Elektroda Zn sebagai anoda
Potensial standar sel adalah 0.04 V
Zn mengalami Oksidasi
Reaksi sel : 2 Ag+ (aq) + Zn → 2 Ag (s) + Zn2+ (aq)
