A student is designing an experiment to test water from various sources for the presence of lead (a heavy metal that can harm humans if ingested). The student will collect water samples from the school drinking fountain, home kitchen tap, and a nearby river. To test for lead, the student will use a solution of iodide ion. The student obtains some distilled water (known not to contain lead) and adds the iodide ion; the water remains clear. Next the student obtains a solution known to contain lead from the chemistry laboratory; when iodide ion is added to this sample, a bright yellow solid forms. Pose a testable hypothesis for this lab.
