Question:
We noted that a tin-plated steel can corrodes more quickly than an unplated steel can. In cases of galvanic corrosion, one cannot expect standard conditions. Suppose that you want to study the galvanic corrosion of tin-plated steel by constructing a cell with low concentrations of the ions. You have pieces of tin and iron. You also have a solution of tin(II) chloride that is 0.05 M and one of iron(II) nitrate that is 0.01 M.
(a) Describe the half-reactions you construct for this experiment.
(b) Which half-reaction will be the anode and which the cathode?
(c) Based on the solutions you have, calculate the cell potential for your experiment.
