Sketching and labeling a galvanic cell: Design a galvanic cell that uses the redox reaction Fe(s) + 2Fe^(3+)(aq.) rarr 3Fe^(2+)(aq.) Identify the anode cathode half-reactions and sketch the experimental setup. Label the anode and cathode, indicate the directon of elecron and ion flow, and identify the sign of each elctrode. Strategy: First sepreate the overall cell reaction into anode (oxidation) and cathode (reduction) half-reactions. Then, set up two half-cells that use half-reactions, and connect the half-cells with a conducating wire and a salt bridge.
