Solution: Solutions of 0.00024 M aqueous sodium iodide and 0.0054 M aqueous lead (II) nitrate, Pb(NO3)2 are mixed together. Which of the following is the most likely result that a student would observe? Assume no volume change. Ksp of Pbl2 is 1.4 x 10-8. A. All ions remain in solution and no precipitate is observed. B. A precipitate of sodium nitrate, NaNO3, is observed. C. A precipitate of lead (II) iodide, Pbl 2, is observed. D. The mixture results in the formation of a saturated solution at equilibrium. E. The Nal and Pb(NO3)2 solutions do not mix and two separate layers are formed.
