Using the standard electrode potentials given in the Table 8.1, predict if the reaction between the following is feasible:

Fe3+(aq) and I–(aq)

The possible reaction between Fe3+(aq) and I–(aq) can be represented by the following equation: –




E° for the overall reaction is positive. Thus, the reaction between Fe3+(aq) and I–(aq) is feasible.
