Question
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(g) + 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 → H2(g)
0.00 V
Ni2+(aq) + + 2e → Ni(s)
-0.26 V
Fe2+(aq) + 2e¯ → Fe(s)
-0.45 V
nickel wire (solid nickel)
none of these
охygen gas
aqueous copper(II) acetate
