The iodide ion concentration in a solution may be determined by the precipitation of silver iodide. Ag+(aq) + I-(aq) -> AgI(s) A student finds that 24.84 mL of 0.5340 M silver nitrate is needed to precipitate all of the iodide ion in a 50.00-mL sample of an unknown. What is the molarity of the iodide ion in the student's unknown?
