Iodometric titration of copper

Iodometric determination of copper is based on the oxidation of iodides to iodine by copper (II) ions, which get reduced to Cu +. Comparison of standard potentials for both half reactions (Cu 2+ /Cu + E 0 =0.17 V, I 2 /I-E 0 =0.54 V) suggests that it is iodine that should be acting as oxidizer.
