Question 1

Based on the half-reactions and their respective standard reduction potentials below, what is the standard cell potential for the reaction that is expected to occur?

Fe3+(aq) + e- → Fe2+(aq)

0.77 V

Sn4+(aq) + 2 e- → Sn2+(aq)

0.15 V

Pb2+(aq) + 2 e- → Pb(s)

-0.13 V

◦ 1.03 V
◦ 0.90 V
◦ 0.28 V
◦ 0.64 V

Question 2

Based on the half-reactions and their respective standard reduction potentials below, which addition to an aqueous solution containing Fe(NO3)2 will result in a reaction under standard-state conditions?

O2(g) + 4 H+ +4 e- → 2 H2O(l)

1.23 V

Fe3+(aq) + e- → Fe2+(aq)

0.77 V

Cu2+(aq) + 2 e- → Cu(s)

0.34 V

2 H+(aq) + 2 e- → H2(g)

0.00 V

Ni2+(aq) + + 2 e- → Ni(s)

-0.26 V

Fe2+(aq) + 2 e- → Fe(s)

-0.45 V

◦ aqueous copper(II) acetate
