ANSWER :
If we add iodine ions in to a lead ion solution , a solid PbI2 precipitate will form ,then if add more iodine ions , the solid form will dissolve due to the formation of complex ions.
This behavior of lead and iodine can be explained by the following reactions and its equilibrium constants :
