Question

Use the galvanic cell reaction to answer the question.

Zn(s) + Br2(aq) → Zn2+(aq) + 2Br-(aq)

Which option shows the oxidation half reaction in this cell?

Answer 1

The oxidation half reaction in this cell is:

Zn(s) → Zn2+(aq) + 2e-

Answer 2

a
Br2(aq) + 2e- → 2Br-(aq)

b
Br2(aq) → Zn2+(aq) + 2e-

c
Zn(s) + 2e- → 2Br-(aq)

d
Zn(s) → Zn2+(aq) + 2e-

Answer 3

The correct option showing the oxidation half reaction in this cell is:

d
Zn(s) → Zn2+(aq) + 2e-
