Below are sample questions representative of the exercises included on this worksheet and related 11.114 Standard Reduction Potentials and Cell Voltage skill assessments:

Problem 1Difficulty: Mastery

A theoretical standard-cell comparison includes Al(s), Fe(s), Cu²+(aq), and the Cl2(g)/Cl^-(aq) half-cell. Given E°red(Al³+/Al) = -1.66 V, Fe²+/Fe = -0.44 V, Cu²+/Cu = +0.34 V, and Cl2/Cl^- = +1.36 V, which design gives the largest positive E°cell?

AFe as anode and Cu²+ as cathode reactant, E°cell = 0.78 V

BAl as cathode and Cl^- as anode reactant, E°cell = -3.02 V

CFe as cathode and Cu as anode, E°cell = -0.78 V

DAl as anode and Cl2 as cathode reactant, E°cell = 3.02 V

Solution & Explanation:The largest positive voltage uses the lowest reduction potential as the anode pair and the highest as the cathode pair. E°cell = 1.36 - (-1.66) = 3.02 V.

Problem 2Difficulty: Mastery

A cell uses Pb(s) as the anode, E°red(Pb²+/Pb) = -0.13 V, and an unknown cathode. If E°cell = +0.67 V, which cathode reduction potential is consistent with the data?

A-0.80 V

B+0.67 V

C+0.54 V

D-0.54 V

Solution & Explanation:Use E°cell = E°cathode - E°anode. 0.67 = E°cathode - (-0.13), so E°cathode = +0.54 V.

Problem 3Difficulty: Mastery

Which statement correctly connects reducing strength to standard reduction potential for metals?

AA metal with a more positive E°red for Mⁿ+/M is generally a stronger reducing agent.

BA metal with a more negative E°red for Mⁿ+/M is generally a stronger reducing agent.

CReducing strength is unrelated to E°red values.

DOnly ions, never metals, can act as reducing agents.

Solution & Explanation:A strong reducing agent is easily oxidized. Metals paired with more negative reduction potentials tend to be oxidized more readily.
