Question 1

What is the reduction half-reaction for the following overall cell reaction?

Ni2+(aq) + 2 Ag(s) → Ni(s) + 2 Ag+(aq)


◦ Ni2+(aq) + 2 e- → Ni(s)
◦ Ni2+(aq) + e- → Ni(s)
◦ Ag(s) + e- → Ag+(aq)
◦ Ag+(aq) + e- → Ag(s)

Question 2

The iron content of foods can be determined by dissolving them in acid (forming Fe3+), reducing the iron(III) to iron(II), and titrating with cerium(IV):

Fe2+(aq) + Ce4+(aq) → Fe3+(aq) + Ce3+(aq).


Identify the two half-reactions in the above reaction.
