Probably what your instructor (teacher) expects you to find out is Iodine is used to test for lead in water.
However there are other things
Thallium is very similar in its physical properties to lead; it resembles lead chemically inasmuch as it forms an almost insoluble chloride and an insoluble iodide

Can also identify silver and bismuth although don't think these are usual uses
Try Wikipedia and search for insouble iodide

Iodine is used in chemistry as an indicator for starch. When starch is mixed with iodine in solution, an intensely dark blue color develops, representing a starch/iodine complex. Starch is a substance common to most plant cells and so a weak iodine solution will stain starch present in the cells. Iodine is one component in the staining technique known as Gram staining, used in microbiology.

The only one I can think of is Hydroiodic acid.
