Question 4 07 1.5 pts What is the concentration of Pb2+ in a saturated solution of PbCl2 in 0.10 M KCl solution. (Ksp = 1.4 x 108)? Why is [Pb2') in this question (smaller/larger) than in Question 3? Hint: What is the initial [CI] before PbCl2 is dissolved? because the presence of chloride ion prevents the dissolution 1.4 x 10M of PbCl2 1.5 x 10M same as in Question 3 1.4 x 10-M, because the presence of chloride ion slows...
