Question 1

For the galvanic cell reaction, expressed below using shorthand notation, what half-reaction occurs at the anode?

Fe(s) ∣ Fe2+(aq) ∣∣ Cd2+(aq) ∣Cd(s)


◦ Cd2+(aq) + 2 e- → Cd(s)
◦ Fe2+(aq) + 2 e- → Fe(s)
◦ Cd(s) → Cd2+(aq) + 2 e-
◦ Fe(s) → Fe2+(aq) + 2 e-

Question 2

For the galvanic cell Pt(s) ∣ Sn2+(aq), Sn4+(aq) ∣∣ Cd2+(aq) ∣ Cd(s), what is the function of the Pt(s)?
◦ Pt is the cathode and does not appear in the overall cell reaction.
◦ Pt is the anode and is a reactant in the overall cell reaction.
◦ Pt is the cathode and is a product in the overall cell reaction.
◦ Pt is the anode and does not appear in the overall cell reaction.
