Based on the half-reactions and their respective standard reduction potentials below, which
element or ion will reduce an aqueous solution containing Fe3 (aq)?
O2(s) + 4H* + 4e 2H20(1)
1.23 V
Fe3 (aq) + e→ Fe2*(aq)
0.77 V
Cu2*(aq) + 2e -→ Cu(s)
0.34 V
2H*(aq) + 2e → H2lg)
0.00 V
Ni2*(aq) + + 2e Ni(s)
-0.26 V
Fe2*(aq) + 2e→ Fe(s)
-0.45 V
O aqueous copper(Il) acetate
O nickel wire (solid nickel)
O oxygen gas
O none of these
