A. Anode: 2Cl−(aq) → Cl2(g) + 2e−
Cathode: K+(aq) + e− → K(s)

B. Anode: Zn(s) → Zn2+(aq) + 2e−
Cathode: Cu2+(aq) + 2e− → Cu(s)

C. Anode: Zn(s) → Zn2+(aq) + 2e−
Cathode: Cu(s) → Cu2+(aq) + 2e−

D. Anode: Cu2+(aq) + 2e− → Cu(s)
Cathode: Zn(s) → Zn2+(aq) + 2e−

@aaronq Can you check my answer?

jfraser · Answer

it can't be C, because both the reactions listed for option C are oxidations. Do you see why?
